While I OBVIOUSLY use Wordpress for my self hosted blogs, I prefer blogspot for my free ones. It's so quick and simple that it's a joke, and it's what I started out on so it kinda has a special place in my heart. Blogspot's allright, nothing wrong with it. That said, I'd hate to run only free blogs - after all, do just that and you could wake up one day with your whole business gone. That would suck.
