I do, but what I like is close enough to WotC's that the same general topics of interest keep coming up, only they come up in the context of WotC's game because it rules the roost. On the occasion there's a conversation about a non-D&D style game I like (like Cyberpunk, L5R classic, or many non-narrative supers games), or specifically about a D&D-style game I favor (like Level Up, ACKS, DCC, or the Without Number series) i do participate. But such conversations are far less common that anything using WotC's game as a context.
