The first thing you should do to advertise your blog is register at this site and then nominate one or all of your blogs. By placing all of your blogs into the nomination process you enable them to be voted on by others frequenting the site. Whether you win any category or not it is great advertising just to have votes. Votes from a site like this lend credence to whether your site is valuable or not. You also open your blog up to being promoted to other blog owners who could then post about you if they like what they see.
