I think the main thing that stops many products from gaining momentum is that point exactly – when you already have "something" but need to find your first adopters who will start using that thing.
This site aims for this problem, and hits where it hurts, because there's a lot of info on the net about how you can get your first adopters, but it usually doesn't refer to successful cases or doesn't let you compare them to come up with your plan.
This product will be huge, I suspect.
