As is probably obvious by my lack of friends and general rambling, this is my first time using online communities. I do teach online so much of my time is taken up with subject specific forums - very different to this. I also suffer from RSI so I try to limit my computing time... My first impressions of all of this is that I've entered another universe. I feel like I'm peering over the edge of something vast. I never realised there were so many groups, forums, blogs. And yet it's all quite dispersed - like the universe, forever expanded.
