Hi, someone sent me a personal message on this site about his own site called grupl. I thought I would plug it here since the spirit of this thread is about advertising your blog..
Group Powered Content: Grupl
Bascially it is a site with a voting system, similar to sites such as digg, but foccessed on blog articles. You submit an article, and people vote for it. It seems like it could be a good way to get traffic.
