I use reddit to discuss stories that only people in my town would discuss (r/stlouis) or to discuss things about the local sports team that only the people in my town would discuss (r/stlouisblues). Neither of those places are particularly toxic and there isn't really a better place on the web to discuss those things.
But that's the thing. There is no actual real reason to go on Reddit.
There's no actual real reason to do just about anything. But reddit is the best place for certain types of conversation.
Edit: The default front page really is a piece of crap.
