Marketing director Doug Lombardi talks about Source, Steam and Half-Life Episode 1. FiringSquad: First, Valve will have a booth at this year's GDC expo. What will the company be demoing at their booth both in front of and behind closed doors?

Doug Lombardi: We're actually not demo'ing a thing. We're simply setting up a booth with a few meeting rooms so we may speak with anyone interested in utilizing Steam, the Source engine, or maybe working at Valve.
