Another thing is that there happens a lot of developing behind the curtains.
The more someone show his skills in the forum the more he faces requests to help in one or another way, and sometimes find people who ask him for paid work.
As soon as they found a way to earn money more frequent, they don't appear as active on these forum as they are expected to do.

I'm personally now working on a project that wouldn't last more than three months on a professional base, but lasts now from November of the last year and still isn't finished.

You won't get a start and a team without a good concept and good skills in at least one of the required tasks of a game production.
And, probably, you need already a prototype that the guys around here like to play to find a team.
If you as an artist present in this forums a set of models(with all included: skinning, animation, texture) and scenes(texture and shadowing) that show an impressing atmosphere, a certain uniqueness and a fitting visual concept for a small game, then you most certainly find others who are willing to cooperate, but the most skilled users are already busy with one or another project.
