Real life is a very different use case. Better, but also a lot harder. I've never actually tried reddit, but my impression is that it's more of a traditional forum, but lots of them.
At the moment, G+ers seem to be gravitating towards MeWe.
One can have a private, invite only subreddit and one can choose all the moderators of the subreddit. I think that if you use reddit's native mobile or web page css they push ads on you so I don't use either of those.
