i use wordpress on all of my blogs and love it. fuck blogger/blogspot. it's SHIT.
fuzebox: Wordpress is easy as hell to change code. It's SO template based that if you know php a little jerking WP around is cake. mrkris and I have made MANY changes to ours without any problems
I whole heartedly recomend wordpress. and theres shitloads of templates if you're not familiar with making your own.
