Follow Me, Follow You

What’s the “right” number of followers/followees on Twitter? I’ve previously pondered what might be the ideal number to have in your network, but there is clearly no one right answer. The right number to have is whatever works for you. Some have suggested that Dunbar’s Number – around 150 – is about right, but my own Twitter network has been steadily growing to almost double that and it still seems to be worthwhile and working for me so, for now anyway, I’ll let it keep growing. Whenever someone follows me I’ve gradually developed a process to help me decide whether I follow back or not… basically I click the link to go to the new followers page, and look for a couple of key bits of information. Are they educators? Are they actively involved in ed-tech? How many do they follow? How many follow them? How often do they update? Who do they follow?  Taking everything into account, if it looks like this person can help add value to my network I’ll follow back. (I know that sounds one-sided, but they’ve already made the decision to follow me so from their point of view I can only assume they see some worth in doing so.)

For quite a while now I’ve been getting a steady stream of Twitter notifications saying “such-and-such is now following you on Twitter”, often several every day. It’s nice to think that people want to follow you because they feel you add value to their network, but what’s the deal with these people who just collect and follow anybody? Over the last few weeks, I’ve been noticing that more and more of these follow notifications come from random people who appear to simply follow anyone.

Take a look at the screen grabs above. These three all arrived tonight and when you look at the following/followers ratio it’s pretty one-sided. For example, look at the person who is following 14,972, but only being followed by 699… that’s a ratio of over 21:1. For every person that follows them, they follow over 21 others. The other person following 1,814 has 52 people following them, that’s an even less balanced ratio of 34:1. (with only 8 updates… what’s the deal with that!?)

My own follow/follower ratio is currently 287/342, or .83:1, meaning I get followed by more than I follow. Although there is no right or wrong to this, to me it seems fairer when your ratio is relatively close to 1:1 (or at least not ridiculously unbalanced like 34:1!)

Why would anyone want to follow 14,000 people? What possible good could that do? You couldn’t possibly be getting any real signal out of all that noise could you? Perhaps if you follow a large number of people you might like to leave a comment about it.

I used to feel obligated to “keep up” with Twitter, but I’ve decided that I need to think about it like a river flowing past me… I don’t need to read every single tweet. When I had 50 or so people in my network I used to be able to do that, but as it’s grown I now use Twitter differently, just to give me a sense of the zeitgeist of what’s happening out there. I don’t bother reading every single post now – I just can’t, there’s too many – but I do scan through many of them as they pop up in Twitterific or Twhirl. I feel like I only need to find that occasional gem of a url, read an occasional worthwhile insight, contribute occasionally to a conversation going on, or catch the latest snippet of online gossip to make Twitter work for me.  With nearly 300 people on my follow list I definitely use Twitter differently now compared to how I used to use it when there were only 50 or so on my follow list, but it’s still worthwhile being part of it. I have just found I need to be more relaxed about it, less concerned with “keeping up”, and I’ve learned to be content with what I do get from Twitter rather than worrying about what I might be missing.

I’m sure this is all just part of an evolutionary process of how Twitter works for you depending on how many are in your network, but I still find it hard to imagine what use you’d get from having thousands on your follow list.

 

Becoming a Moodle Dude

Julian Ridden training in MoodleSome things make you proud to be Australian.

As a nation with a relatively small population we have achieved some excellent results on the world stage. Sport. Science. The Arts. Even technology.

One of the real success stories of Australia’s technology achievement is Moodle. As an open source eLearning platform, Moodle started its life as a thesis project by a guy named Martin Dougiamas at Western Australia’s Curtin University, and has quickly grown into a major player in the rapidly growing eLearning world. Importantly, Moodle has been designed from day one to support learning using a social constructivist philosophy. Dougiamas belief is that people learn best when they are networked and connected, able to share and communicate ideas, and this belief underpins everything about Moodle’s design.

I am currently half way through a 4 day Moodle workshop and the more I learn, the more amazed I am at the maturity and depth of Moodle. It’s a relatively young piece of software that is growing rapidly thanks to a global community of developers. Although I have dabbled with Moodle a few times in the past, the last two days have really opened my eyes as to the power of what it offers. It is really powerful. And the next two days will focus on the backend administration stuff so I’m sure I’ll be equally as blown away.

Thankfully, we’ve had Julian Ridden as our trainer. Julian is the ICT Integrator at St Ignatius, Riverview and is arguably one of Australia’s (and possibly the world’s) most knowledgable Moodle guys. His explanations, advice and insights into Moodle have been priceless. I’m especially thankful that he is not just a techie (although he’s pretty darn good that that side of things too), but he is also a teacher and everything he’s been sharing about the use of Moodle comes from a really sound pedagogical background that can only come from someone who is still in real classrooms every day.

My new school, PLC Sydney, has a fairly large Moodle installation which aims to manage a lot of our course material and although it’s well developed and quite extensive, I’m realising now that there is lots of room for improving it. Like many tech developments, especially in a school environment, our Moodle has grown in a fairly organic way and probably suffers from a lack of design. I’m realising that, as with all web design projects, thorough planning needs to account for at least half of the time and effort involved in putting it together. As I return to school next week thinking about a complete overhaul of our Moodle server, I’m seeing that we really need to think it through very thoroughly before we start building anything.

One of the things I was most struck by is the modular, extensible nature of Moodle. I thought it could just do the handful of things that a standard Moodle install comes with – forum, wiki, chat, quizzes, surveys, and so on. These activity tools are very useful of course, but Julian has been showing us the huge library of resources at www.moodle.org… literally hundreds of extra modules that can be dropped in to the back end to add more functionality to the standard Moodle installation. Integration with RSS and Web 2.0 tools, podcasting modules, all sort of interesting blocks, activities and filters… I’m just gobsmacked at how hugely flexible this tool is!

Moodle just released version 1.9 a few days ago, and it has quite a few improvements over 1.8. Most notable of these is the integrated teachers markbook, which has been supercharged to now have all the features a teacher could want in a markbook (including support for outcomes!) but there are quite a few other neat new features worth checking out too.

I’ve installed Moodle locally on my MacBook Pro using the MAMP engine, so I now have access to the full Moodle installation, inclucing the backend database, to play with. I’m dabbling away, adding stuff, breaking stuff, learning how it works, before I get focussed on rebuilding the PLC Moodle. If you want to dabble with Moodle too, I recommend installing it on your own computer and playing with it.

I’m looking forward to becoming a much more accomplished Moodler!

Living in the Cloud

Until fairly recently, most of my computing was done locally using “real apps”. By this, I mean they are cllient-side applications installed on the hard drive of my own computer. I guess I’ve always liked the speed and convenience of having my applications – tools like Office, email, calendar, feedreader, etc – right there on my hard drive where I could get to them running at full local speed. Once you’ve been spoilt by the responsiveness of locally-run apps, web apps that run from the Internet just aren’t as snappy.

Of course, many will say that locally installed apps are old skool; that if you really think with a Web 2.0 mindset, then running your key software directly from the Internet makes more sense. The world is certainly trending that way, with a proliferation of Web 2.0 apps that now run directly from “the cloud” and computing devices designed to work this way, such as the Macbook Air. Computing in the cloud started with obvious applications like webmail, but have now extended to office productivity software, photo editing, even video production, all workable with nothing more than a web browser and a broadband connection.

Life is all about compromises and finding the right balance. Although I’ve been resisting cloud computing for a while, my circumstances changed recently and I decided to make a switch to see if I could manage moving my basic tools off the desktop and into the big blue nowhere.

The real trigger for making the move to the cloud was an increase in the number of computers I was working on every day. My main machine has been a Macbook Pro, which I essentially did everything on. I also owned a 20″ iMac on my desktop, but that was used mainly for editing podcasts and storing my media with iPhoto and iTunes. I really didn’t spend that much time on the iMac, although it’s a beautiful machine to use. Since we moved house recently though, I’ve been using the iMac a lot more, even more than the MacBook Pro. Then when I started the new job I was given a Toshiba 12″ Tablet PC as my work machine.  It became awkward to manage all my stuff since it was now spread across three different computers, all using locally installed software applications. Suddenly, locally installed apps were making a whole lot less sense, with important emails and documents never on the machine I happened to be using, my work calendar and my personal calendar getting out of sync on different machines, and I figured it was time to start looking for a better way to consolidate my digital life.

So here’s the problem… I had three machines grabbing email from 5 different accounts, two calendars that needed to be kept separate but I also needed to cross reference them against each other, a writing project which required collaboration with another writer in a remote location, and a group of RSS feeds that were being picked up on three different machines. My digital life was a mess…

It was finally time to submit to the cloud computing model and take all of these disparate bits and move them to cyberspace, where I could access them from any computer. There are many tools to enable this, but I decided to go with Google’s tools since they seem to work really well together and one login would give me access to everything… Gmail for my email, Google Reader for my RSS aggregator, Google Calendar for my appointments, and GoogleDocs for my documents. I won’t labour the point about these tools since I assume most people are already pretty familiar with them, and using web apps is hardly a revolution, but I did want to mention a few tweaks and tips that really made the move to the cloud so much more workable for me.

First, Gmail. For a long time, I’ve been a heavy user of Entourage, and more recently Apple’s Mail, and really liked them.  Although I’ve had a Gmail account for ages, I mainly used it just as my secondary mail account. My real mail comes in on chris[@]betcher.org and I didn’t really want to switch that. Thankfully, Gmail has the ability to hook into my ISP’s account and pull my regular mail into the Gmail service. This means that I can now stick to my long term email address via my regular ISP but get to it with the convenience of Gmail’s web-based anywhere-access. I added another POP account I had and I can now send and receive mail from any of these addresses via Gmail, from any machine, with the added advantage of a powerful spam filtering service freely supplied by Google.

Second, my feed reader. I tossed up whether to use Google Reader, Pageflakes, NetVibes or Bloglines. The new Bloglines beta looked good, but had a few annoying behaviours. After testing each system for a few days, I decided on Google Reader. Once it’s set up, it works very smoothly with Flock – my browser of choice – to add RSS feeds. The way it displays feeds is really intuitive and each to understand, and it was able to import the OPML file from my desktop feedreader, Vienna. So far, I’m impressed with Reader and I can now check my feeds from any machine, and keep them all in sync.

Google Docs are wonderful. Although I’ve got a Microsoft Office Specialist certificate and am a pretty capable “power user” of MS Word, like most people I mostly use it to type up fairly simple documents. Google Docs may lack many of the features of Microsoft Office, but they are mostly features I don’t use anyway, and the ability to collaborate on documents with other people more than makes up for the missing features. Working across several machines, the ability to have all my documents accessible from one place – the Internet – is an incredibly useful concept. But I was really won over with Google Docs when I saw the Firefox plug-in called GDocs Bar. This plug-in gives one-click access to Google Docs for both accessing your online files as well as uploading new ones. GDocs Bar makes Google Docs so much more functional.

Finally, the other big problem was that my personal calendar was being managed by iCal on my MacBook Pro, and my work calendar was being managed by Outlook on the school’s Exchange server. This made it hard to look at both my work and personal events together, as both were kept in separate places although they had overlapping events. The killer link in making the move to the cloud came with the ability to sync both the iCal and Outlook calendars into a single Google calendar. To achieve this, I used a $25 app called Spanning Sync to synchronise iCal to my Google calendar.  It works fantastically with perfect two way syncing. I then used the free Google Calendar Sync tool to do a two way sync of my work Outlook calendar into my Google calendar. The end result is that my online Google calendar now pulls data from my two separate calendars and displays it in real time, in one place, easily accessible from any browser.  This is way cool…

The bottom line is that I now feel I have a really workable cloud computing experience, with all my key information stored in one place – the web – that I can get to from any of my machines. I know there is still plenty of life left in the locally installed software model, especially for the more computationally intensive multimedia applications, but so far I’m pretty impressed at just how easy and effective it has been to move my most commonly used productivity apps to the cloud.

I just hope we can trust Google.
