Exactly what I suspected.
Why would only one person see this? And of all places, why would they post it on 4chan?
You'd think anyone who cared enough to take a screen grab of something on the Steam site would be an active member of their community and would post such things there first.
I don't understand why any site would post such a thing without verifying it first. Oh wait... they got a ton of hits because of it... that's why.
