To me, the answer is simple- very simple, I love Blogger. It is free and it has unlimited bandwidth. You can use it very easily. In fact, you do not need any kind of technical knowledge to blog in Blogger. That is perhaps why Blogger is so popular. It uploads images very fast and the new blogger also allows you to give labels. Google search loves Blogger and you can integrate Adsense in Blogger without any problem.
So, why I should not vote for Blogger? By the way, I am a fan of Movable Type too.
