Digg Clones
A great idea spawns a million permutations. It’s not quite a million yet, but the 3spots blog has a nice list of “all” the digg clones in existence.
They also link to some open-source software to make your own digg-style site, add tagging to any project, and do other digg-style things. A nice compilation of resources here.
