What really blows my mind is how simple and obvious MakeBot is. In short, MakeBot is an IM chat bot - it looks like any other IM buddy.

John Battelle's mind blows over hackerish IM bots that talk to RSS feeds. I'm not sure how mind blowing this is, as people have been doing this stuff on IRC for years, but maybe it will inspire someone out there to do a project.... It might be a nice way to avoid dealing with crappy web browsers in phones, but MemeStreams works rather well on my sidekick...
