Caveat Lector: While I play on both Digg and Fark, I have a greater affinity for Fark/Total Fark. Its just where I went first. I've hoisted a tasty beverage with many of those loveable farkers.
If Digg added moderators and allow users to, oh i don't know vote, on links before they get posted then essentially you have what we have on Fark/Total Fark. Total Farkers get to view all links before they get posted to fark.com. We even get to vote on them now. Not to say that we users have the final say in what gets posted. There is that added overlay of Mods and Admins that add a bit of surprise or control depending on how you look at it. To be honest, this is fine by me. They keep it tidy. I just find it interesting that Digg may morph into Fark.
