Do you want just a blog?

Wordpress.com is free. I really like typepad. IF wordpress is still via invitation I can send you an invitation.

If you are looking for a web host where you can do more than just blog, MOST webhosts will install it for you. And for non adult the hosting is dirt cheap.

I think typepad is $15 a month, but you can create a very good blog with a lot of features and its real easy.

Wordpress.com is hosted on their servers and is free. But I havenmt looked into the site that much to see how far you can customize tehh thing on their servers.

LMK if I can help.
