Funnily enough, I'm not subbed to /aww, /adviceanimals, or /funny; if I feel a need for some /aww worthy content I just head over to the Daily Squee on the Cheezburger network. I occasionally like /askreddit, but only occasionally anymore. The biggest issue I have is all of the way-over-sensationalized "news" headlines, which are then linked to right-wing and/or left-wing nutjob conspiracy theory blogs, but treated like they're the last verifiable source out there. I mean, did you know that FEMA, under the direction of DHS, has set up dozens of concentration camps throughout the country, and is just waiting for the word from President Obama to start rounding up Americans and locking them up?* Or how about that new budget bill that Congress just passed that strips away the right of any third-party organization to post congressional or senate bill text online?**
More and more these days I get annoyed when on one hand, the people posting news links are constantly bashing Fox News for being biased and sensationalized, and then the next minute they turn around and link to something like "PeopleOKwithmurdingAssange.com" or Huffington Post, which recently ran a full-page article on a flamewar between two redditors (the fight between Shitty_Watercolor and who cares who else) - because that's high caliber news right there.
Though I did recently find a couple of really cool subreddits, so I'm sure I'll be sticking around if only to watch those; /militaryporn, and /warshipporn, both from the reddit sfw porn network.
*If you swap out the term 'concentration camp' for 'emergency disaster relief shelter' you might have more luck finding these places. You know, so FEMA doesn't have to rely on the possibility of finding a football stadium or cruise ship to house evacuees.
**Actually, the text of the bill said nothing about digital rights as they relate to the posting of bill text by 3rd party websites. The only mention of such an issue was in the committee hearing notes, where they discussed the exact opposite of preventing such a practice, and in fact discussed steps needed to put all bill and official communication text into XML format instead of PDF, so that it would be easier for 3rd parties to post the text online.

Already done. Done. And done.
The bigotry, racism, transphobia, circlejerking, 'hilarious' novelty accounts and let's not forget victim shaming when it comes to rape is rampant in almost every corner of Reddit.
/r/askscience is the closest thing to a clean subreddit due to its heavy moderation.
Also, this.
