I recently started using tumblr and its mind blowing how much they allow you to do for free. There have very little limitations, if any. They allow you to put ads on you blog with no string attached AFAIK, custom domains (other do it too).

I was hoping that they would allow API access to password-protected blogs. I use marsedit to post on my blog, but can't do it on my private blog.
