Adding Steam to the (games) services

I would like to see 'Steam' added to the list of services.

The largest digital distribution offering of PC-Games with all imaginable community aspects present. And like Wii, PSN & XBL, a pain to remember (or share) your user-ID. (plus, I think it has a larger userbase than the current services combined)

For example: http://steamcommunity.com/id/Hooker/
