If you're looking for ways to advertise your site or blog I'd highly recommend http://www.url-preview.com It allows you to create a URL preview page for every link you post on the net. You can insert your own ad for your site to this preview page so that every time someone clicks on one of your posted links, they'll go to your preview page where they'll see your ad before they continue to the link you've posted. I use it a few times a week when I find an interesting link and it brings in a decent amount of traffic to my blog.
