It's always nice (as a recruiter) to see technologists actually write something designed to be helpful to recruiters, as opposed to the volumes of material that simply complain about being contacted so much because they are so popular. Junior level recruiters tend to contact everyone, and the industry is rather lazy overall because they are taught that it's a pure numbers game.
Thanks for taking the time to give some tips and explain some things to people who likely didn't know about GitHub.
