I'm gonna do it this weekend, probably at the wee hours so if I fuck something up, most folks won't see it. What the hell, if it sucks it'll give me something else to bitch about.
Thanks for all your comments.
Update 05:40 Thursday:
I don't know if anybody else noticed but Blogger has been moving Atrios since last night (I've been getting this page when I head over there). Seems to me there might be a bit of a problem? I'm sure Atrios will let us know when (if) he gets up and running again but it's making me rethink doing the move.
