Hi,
I have no doubt that dealing with a whole community is hard 
I have helped my brother in writing a couple libraries (he just wrote on this topic, he's Federico and publish on github at federico-galli (Federico E. Galli) · GitHub).
My github-fu is certainly low, I didn't notice the addition of Organizations to github, I thought it was just a word you used to describe the repository.
Now I see that is indeed possible to have a fine-grained permissions' control.
I'd prefer however that the arduino IDE would use the database you mentioned instead of just this repository to import libraries.
Thanks for your work on Arduino,
Riccardo
