I am with @pest . rethinkdb's github issues becomes my daily read, along with Github's Atom repo.

Just look at the issues , how they handle them , how their professional responses , and how quick they resolves issues after issues with full co-operation between issue owner , users and contributor. They guide contributors as well. And it is really Addictive , be warned.
