Valve announces Steam Reviews, a crowd-sourced review system

I can see it now: countless keyboard warriors attacking a game because "it has lag" or the "graphics are crap", but Valve has just announced Steam Reviews, a crowd-sourced review system on Steam.

Gamers can review any game on Steam, where Steam Reviews will show ratings from those reviews, and is in beta right now. Better yet, you'll be able to do some Review Inception, where you can rate other gamers' reviews. This could work well, but it could also open Pandora's box, too.
