I'd love to take some time to unpack the site, and they've invited us to participate, but truth be told I'm just too busy to give it a test run.  If you have, let me know what you think.  These kinds of sites are known as 'collaborative filtering' sites, where the power of the crowd ranks and orders content.  They will be key to how you consume news in the Web 3.0 era.
