Yeah, I feel you on this. One of the problems with FCC is that it's too popular, and thus it's easy to get lost in the crowd, especially on the gitter chat. After all, you can't possibly connect with thousands of people all at once!
It is possible, but I think takes repeated meaningful engagement* here on the forums and in the chat channels. Eventually you learn something about frequent posters, and they learn something about you. But in the interim it can feel lonely: other frequent posters may ignore you for a practical reason: they don't know you or know if you will stick around. No one wants to invest time in someone that will just bail in a few weeks.
Chingu will help because of the pure numbers game.... But it's not a panacea. I'd have all the same recommendations for connecting there as I do here.
*: Not passive listening, not just chiming in with "me too", not just asking for help. IMO the best way to meaningfully engage is to try to help other people, though this too can feel lonely if they accept your help and never return.
