I just switched from Blogger to WordPress about three weeks ago (see post: http://www.erinat.com/blog/index.php?p=123). Although it did take be a couple of days to move all the entries into the database, I love the look and feel of WordPress a lot more.
It didn't even take long to make quick customizations to the entry screen and the texturize engine.
Since switching I know of at least one of my friends that has also switched (http://www.cupjoke.com/).
Anyway, I'm proud to be using WordPress.
