Maybe this question is so basic and clearly understood that there's no point in even asking, but what is the problem with starting new groups or activity in places like Facebook, Reddit, and Twitter? The implied answer is that people liked Google + for not being those places, that every site or platform has it's own strengths and drawbacks, and in particular dislike for Facebook was part of the Google + appeal (maybe related to perceived privacy issues too, or because friends and family are on there?). All the same I see people asking about how to establish group functions in other places that are very straightforward in Facebook (privacy options, control of membership, sharing features, free access, etc.). Reddit is limited for functionality, with an odd structure, and I don't like Twitter at all, so I guess it reduces to what is seen as wrong with FB.
