Definately...a lot of money can be made from free wordpress and blogger blogs. But as mentioned before, you run the risk of getting them taken down at any time.And you are limited in creativity. If i were you, invest atleast $10 in a domain even if you are using it with free hosting (i used freehostia for a long time). Once your site starts making some cash, you can go and get proper hosting.
