Sure, I'll list a few.
1) My biggest beef is the fact that the layout is shit and the site looks like it was made in the 90's and they refuse to update it.
2) There's only a handful of subreddits I actually enjoy and/or find useful.
3) The people who run the site come off as arrogant and holier than thou, not to mention they have this weird sense of being innovators and torch bearers leading the online world into the future. That's stupid, especially when you consider some of the shit that has gone on at the site and what they really stand for. It's dangerous, scary, ignorant, hypocritical, not to mention illegal as fuck in a lot of ways.
4) And a bunch of other reasons.
As for your second question, I read the news on news sites, and specific community forums/websites for specific topics. There's too much opinion and not enough facts on that site for my liking. Not everyone should have a microphone to give their opinion. imo (lol)
