ZDNet: Comparing Reddit’s karma system to Digg

On my ZDNet blog, I discuss social news site reddit.com with co-founder Alexis Ohanian and compare their collaborative filtering system with Digg‘s.

Reddit may have a jump on Digg when it comes to avoiding groupthink and spam, via a user reputation system it calls ‘karma’. Check out the full story on ZDNet and tell me what you think: is Reddit’s karma system a better – more honest – way to rank stories and users than Digg’s populist approach of ranking by homepage hits? Or do you think Digg has the right approach, but just needs to address the groupthink and spam issues that come with scaling to thousands of users?
