I am looking for a place to meet similar minded gamers to play co-op with. I know Goozex has the playing now tab, but it is severely under utilized. (Left 4 Dead example). Xbox Live has the recent played with list, but I am looking for something more PC based.
Pretty much I just got Borderlands and looking for ways to play with people, but I want to expand the question for generality.
I would prefer finding people to consistently play with, but for sake of generality, answers can be for both consistent and random people.
Note: I am trying to avoid making this question too specific and subject to closing. Comments or edits to properly modify the question is appreciated.
