You used to be so stupid that you thought some of the mediocre posts were funny. Then you got smarter. Well done. Graduate to reddit.
I'm not trying to be mean. I'm being legit honest here. You'll like it better over there. Pick a category you like and try to find a subreddit about it. Do NOT under any circumstances go to any of the subreddits that are "default" or overly popular. Don't go to /r/anime, but instead go to /r/killlakill or /r/k-on or whatever other anime you like. You'll find that segmenting your audience down until you're only surrounded by likeminded people is initially strange but eventually wonderful. THEN if you want to avoid being echo chambered, you simply subscribe to more than one of these places so that you have many places you call home and you don't become inundated with any one community. You do not want to allow any places to change you. You want to be a well rounded person.
Good luck, Anon. By the way, you can name your username something like 283498213598 and nobody will say anything.
