I feel like it's been pretty well established that Tildes is supposed to be a place of discussion with maybe occasional fluff here and there that can be filtered out. But there's a large grey area that I think should be addressed.
I'll take a few of Reddit's subreddits as an example.
I think it's pretty clear that a group resembling /r/aww should not be allowed on Tildes since it is pure fluffing and does not really bring a big quality of discussion to the community as a whole.
But how about a community such as /r/QuitYourBullshit? That could arguably be either unnecessary or a place of good discussion. There's a lot of grey area regarding the quality of that subreddit.
Now, I know what some people might try to say. We shouldn't try to replicate Reddit, and we should instead let the communities grow organically.
Yet, if Tildes is going to grow at all from Reddit, people are going to want to replicate the communities they so dearly loved on Reddit, regardless of quality. People who were active on /r/dankmemes are going to want a /r/dankmemes equivalent here. People who were active on /r/todayilearned or /r/JusticeServed are going to want an equivalent here as well. So the question is: how are we going to deal with the large demand for variably fluffy groups while simultaneously keeping the quality of discussion up?
I think this is a real issue that is going to have to be dealt with before widespread adoption of Tildes can occur.
