Steam gets us all gooey, sells World of Goo for $5

All weekend long,
Steam is selling 2D Boy's
critically acclaimed (and
Joystiq-approved)
World of Goo for $5, which is 75% off the normal going rate. Knowing that, anyone connected to Steam should, at the very minimum, give the demo a test drive.
Truthfully, we can say that
World of Goo offers at least $5 in sticky, sticky fun. For that price, there's really no way one could justify
Goo piracy.
