I saw the JS demos a few months ago and was blown away. It seems like the community is really thirsty for NN tools and materials, and the way you are going about this (interactive JS) is right on the money? Why not engage the community to keep building the site up, then? You may want to look into open-sourcing the entire site + the JS library, it may really pick up steam. Worse case, it breaks apart (can always reclaim it), but the exercise could be a very interesting one.
