So... that was a bit of a break.
You know how it goes. One day off turns into two, into three, into a week. Especially when you've got a big honking essay to do. Especially when you're going to treat the essay seriously this time.
During my absence I did bring back comments. I've outsourced to Disqus, because it's a lot easier than writing my own system from scratch again. If you like you can head over there to set up a profile/account so that when you leave a comment here it'll have a little picture of you next to it or whatever. It's all about online reputation building. Apparently.
But anyway, feel free to comment. And apologies for my absence. It's not meant to happen, is it?
