The number of forums matters a great deal in keeping users active. Having generalized sections exposes users to see threads that might catch their attention when they wouldn't have otherwise seen them.
In general the fewer the threads the better. Look around at failed and successful communities. Obviously there are exceptions like the motherhood forum Stephen linked. My guess would be that a topic like motherhood is specific enough to draw a large number of users based on it's genre alone as opposed to a general community forum that has no focus.
Sub-forums are annoying as hell to me personally. I don't understand their usefulness at all, they seem to just hide topics deeper and make them less accessible/visible.
"Rarity by itself shouldn't necessarily be evidence of anything. When one is dealt a bridge hand of thirteen cards, the probability of being dealt that particular hand is less than one in 600 billion [1 in 6 x 1011]. Still, it would be absurd for someone to be dealt a hand, examine it carefully, calculate that the probability of getting it is less than one in 600 billion, and then conclude that he must not have been [randomly] dealt that very hand because it is so very improbable." -John Allen Paulos, Innumeracy: Mathematical Illiteracy and Its Consequences
