Knewsroom: A Look at the Latest Social News Site – ReadWriteWeb
What I find really interesting about Knewsroom is that the more you participate and the more the community appreciates and respects your participation, the more power you have to shape the Knews. This is a good way to incentivize regular participation and is the exact opposite of the way Digg treats its most passionate users.
