The advantage of Blogger is that I can get a post up faster than at WordPress. The posting interface is less cloggy to my browser (which is Firefox 2.x because of my crap desktop hardware).
Trying to divine reader stats for this blog is a royal pain with Blogger.
Also, paradoxically, I've always found WordPress to be incredible for getting my posts into Google and other search engine results quickly.
Last, I don't like the way photos are handled here. I can never tell how or when Blogger will resize something -- or the why of it, either.
So, I've imported all of this blog into WordPress as a test.
None of the graphics have been imported -- they simply link back to here to for now.
Should I move or not? Comment!
