If you haven't heard about it yet, well you need to check out Ballhype.
You will soon one way or another.
It's more than just a site which collates articles -- in the same way as it's current parent lowpost.net does. Ballhype joins people together in likeminded groups and allows you to vote on stories. Check the site out and join up... check out this review here, as well.
Don't say I didn't warn you.
