I heard about this over on Bloggeries and I dunno how well the traffic for this service is, but I've been trying it out. Basically, it's a digg for bloggers, and you can "engage" (is that it?) your own posts. The site is about 6 months old I believe, so you can really get in on the ground floor and be one of the top blogs if you try.
