I'm currently looking for Social Media Enthusiasts who are very active in the following medias.. - Digg - Stumble Upon - Facebook and - Delicious Social Media is a good way to increase traffic to your sites, so those who are interested do PM me with your profile URL's
http://www.suexchange.com/ is working well for me in driving StumbleUpon traffic to my sites. You might give it a try.
Lots of fake stumblers on SUExchange though, and you are forced to accept them otherwise you lose a point.
