DotNetKicks is a very interesting site. (Is Digg upset at the theft of look and feel? It's almost identical!)
They have a "Lots of Kicks" blog here and I'm particularly intrigued by how they have combined their revenue generation model with a model to encourage submissions by using your AdSense ID for 50% of the times your story submission is displayed! Innovative!
reBlogger doesn't need submissions, we simply collect the blogs ourselves. 😉
