From our experience with Facebook I would argue that the value in Facebook for your standard gameplay driven MUD would not be that it attracts new players, but that it allows you to interact with players you already have in ways you never could have before.

We often use it to post new code changes, new areas going in or to announce a quest that will be happening in an hour or two. Often after posting that there will be an event of some sort scheduled in an hour or two we get a larger turnout for the quest than when we do not post them on Facebook. All of this of course is done in tandem with the way we've been doing things for the past ten years (posting the changes on the note board in game, etc). IMHO, The biggest value that Facebook gives a mud is that it allows you to interact with your players while they are away from the game.
