I'm not looking to block someone out entirely, just allow myself and others to take hints from the community about what's good and what's bad behavior. Isn't it so much more efficient and helpful to all users if the community has the ability to collectively filter posts and comments via a simple downvote button? It makes finding and rewarding high quality, original content so much easier!

What's this community thing? Wean yourself away from the collective. Don't be a statist...grow a backbone...stand up on your own two feet!

You know who thought that same way? Digg. Go try to post something on Digg now.
