For a long time, I deliberately avoided microblogs like twitter. I thought that they were simply an acknowledgement that people want to be published more than they want to have something to say. However, it would be rude of me to completely disavow the medium without actually giving it a go.
To that end, I may indeed be iamleeg on twitter, as soon as twitter actually finishes processing the signup form.
I'd like to point out that one problem I'm going to have is brevity - I have spent 650 characters telling you what my username is. Constraining myself to SMS-sized wibblings will indeed be tricksy.
