Valve have updated Left 4 Dead today with a patch that adds a lobby browser to the game. This is an important addition to the game; not only does it mean we are able to make our own decisions about where we want to play, but it means that the inevitably great community maps are much more widely available.

Instead of having to go to a map site, downloading a map, and hoping that someone else has done the same, one can simply browse the lobbies for a map they would like, and download it in-game. Hooray for custom maps, and hooray for no longer being treated like children!
