100% agree. But we should never try to force things to "one." There should never be just one community for a topic. That's what Reddit is. "This is the videos subreddit, if you don't like it you don't have a choice."
Good communities will rise. Bad communities will fall. Some communities will attract users because they're big and have lots of members. Some communities will attract users because they're small and friendly. Choice is good. Fixating on there only being "one" of anything is bad.
