Now with the release of WordPress 2.5 I will probably be migrating from Blogger within the next month.
If you haven’t seen what’s new with WordPress, check out the notes on version 2.5. There won’t be much new for your readers, but the wp-admin pages are more organized. I’ve been testing out the 2.5 Release Candidate locally and have been very happy with it.
It’s like they made it…Movable-Typeish.
For users interested in moving a Blogger blog to WordPress, WordPress has included Blogger import for a few versions now. You have to be patient with it, especially for larger blogs, but you should get all your comments, posts, etc.
Maintaining your permalinks is a different story. It isn’t as straightforward, but I have had success locally with this plugin.
