Blogspot, Blogger, Blogdrive, there's loads of em out there ronnie... all different sites, but the same principle
Tigermom - I looked into that for a webgirl friend running on BlogDrive, trying to get her to move to wordpress installed on her site domain... BlogDrive lets you make backups of the whole db, but it's in some whack proprietary format. In theory if you could get the data to export into a workable format, it *should* be possible to do a little modifications to that format for import into something else (matching up the database tablenames, fields, etc.) but it'd be a pain in the ass. If it's a blog that hasn't been up for too awful long, copy/paste each entry might be faster.
Maybe some WP / PHP guru should write a converter plugin to be able to import and convert some of the more popular freebloghost backup formats. I'm not keen enough for that project though!
