Many new AIMbots, as posted by Anil Dash. Check out memepusher which will IM you with the latest MetaFilter links as and when they come up. Brilliant. This is what it's all about.
(And, tangentially, some geezer who writes a column for the Wall Street Journal mailed asking me the story behind googlematic. So I told him. But the story's so dull it probably won't ever get anywhere, although his mooted column about the future of IM services should be interesting. Anyway, that's my brush with mass media for the year.)
