This rabbit hole goes even deeper if you want it to. If you aren't scared of riding the bleeding, buggy edge you can behold the future of PC gaming by registering for the Steam Beta Client or trying out SteamOS, Valve's beta Linux operating system based around Steam. (We even have a guide to building your own $560 Steam Machine with a small footprint and big-time performance.) If you just want to be aware of the latest and greatest Steam happenings, be sure to follow the unofficial Steam Database blog and Twitter account.
And finally, Steam is nothing without games, so be sure to check out PCWorld's guides to finding cheap (or free!) PC games and getting the most bang for your buck during a Steam Sale.
