Hello! I want to ask for advice we have come up against one question and, surprisingly, many can not help. So. Mobile developers have dozens of large professional chats in the cart (they used to be on Skype), there are groups on FB, Linkedin etc. And not only coders live there, but also businesses: owners, managers, producers, bizdevs. And they are quite active there. And what do such communities look like? are there any examples? how to search? And, can you advise someone who has studied this issue?
