Unfortunately, it appears to include node developers who don't have the time or patience to submit a pull request, those who do but whose requests won't be approved, and developers who code in languages other than javascript and who therefore have nothing useful enough to add, among the 'riff-raff'.

Some kind of proof of work is an interesting idea for a site like this, but I wonder if it self-selects for too narrow a domain? I don't know that the correlation between "submitted code" and "provides quality content" are strong enough for this particular filter to provide results worth the effort.
