So WordPress is teaming up with Yahoo! to provide a hosted version of everyone's favorite free personal publishing platform. Sign-up for a Yahoo! small business hosting plan, click "install Word Press", done. This is a particularly interesting deal because just last week Yahoo! announced a hosting deal with Moveable Type. This can't be great news for MT and parent company Six Apart. Who's going to pay for MT when WP is free? A hedge bet for Yahoo! somehow related to Six Apart's TypePad problems? And what's with Yahoo! buying up everything web 2.0?
