YouTube Slam asks you to cast your vote for the next viral hit

Today, YouTube has officially announced Slam, juxtaposing two videos and allowing you to cast a vote for your favourite out of them.  Think Google Slam, only bought into the YouTube era.

This represents a "video discovery experiment" for the site, to help find those videos hidden beneath the clutter that is promoted channels and paid-for viral videos, to help give the average contributor a fairer chance at the gold.
