The next question is to ask yourself what you want from it. Most free hosting have features that just sucks or have very limited features at all. Themes and templates.. If you want a cool site with cool themes, some dont' have any and some do.
MSN spaces is good for a personal page, (I have one), but it's not a blog in the real sense of the word. I would look at www.blogger.com if I wanted a full featured blog.
