Speaking of Reddit, /r/atot, it exists. Not my doing.
Reddit is really what you make of it though like Leros said, there are lot of niche subreddits where people are actually decent.
Others can be iffy especially the main ones. You can't please anyone on the main ones, it's kind of like here, chances are if you post something it's a repost and everybody gets on your back about it. Or if you have an opinion you are better to keep it to yourself or you'll get jumped on, though it's not as bad as here for that.
On the other hand you can get some pretty good conversations on niche sub reddits. People liked my server setup and it stayed near the top of /r/serverporn for a while, I thought that was pretty cool as I did not expect to make the top of a subreddit for that long.
