The chat is not meant for experts only. It is meant for everyone from beginner to seasoned developer.
Putting that part into the advanced developer part is like saying "Don't enter there until you know your ways", which is not what we made the chat for. Saying having "50+" repositories is intimidating and driving you away from chat is like saying you can't friend someone with 500 Facebook friends when you just created your account. You gotta start somewhere and repositories are not an indication for anything as you can create any number of them right after you logged in for the first time anyways. Besides of the 13 people in there only three have more than 10 repos and I am not one of them.
Also we may need to switch to a different chat platform soon anyways as it seems like gitter only allows 25 people in free rooms.
EDIT: I changed the Beginner section a bit. Maybe it is less dissonant like this?
