Want to read Reddit but don’t have the time? Our daily Reddit Digest highlights the most interesting or important discussions from around the social news site—every morning.

  • Did trolls on Reddit drive a man to commit suicide? That’s the claim being made at r/MensRights and r/SubredditDrama. There’s no actual evidence to prove the allegations, however. Unfortunately, quite legitimate skepticism has been buried under a mountain of outrage—so much so that r/SubredditDrama moderator stupidscienceguy was forced to launch a separate thread entirely to urge that subreddit to remain calm. (/r/SubredditDrama)

  • Paul Kiel, foreclosure reporter for ProPublica, probably should have answered more questions in his AMA yesterday, but the responses he did write are well-worth reading. (/r/IAmA)

  • Here’s an interesting idea at r/TheoryOfReddit: use a CSS trick to hide Reddit’s voting tallies until after someone votes. It’s an anti-bandwagoning method: The idea is that readers have a tendency to vote with the crowd, rather than with their own conscience. What prupose do public vote rallies actually serve, anyway? (/r/TheoryOfReddit)

  • What’s the name for the phenomenon where you say something so many times it sounds strange? Semantic satiation. (/r/answers)

  • A question about the diving limits of sperm whales and submarines leads to an interesting discussion on whale biology and SCUBA diving. (/r/askscience

  • Why hasn’t Reddit hired the guy behind the wildly popular browser add-on Reddit Enhancement Suite? Honestbleeps, the guy who created Reddit Enhancement Suite chimes in. (/r/explainlikeimfive)

  • Here’s a fun weekend project for all you photography nerds out there: how to make a camera obscura. (/r/photography)

  • “Someone tell that guy with agoraphobia about this. It’ll change his life,” redditor joetromboni writes in the camera obscura post, referencing this fascinating AMA from a guy who’s only left his house twice in the past year. (/r/IAmA)

  • r/AskReddit has added another rule: “This sub reddit is not a replacement for local emergency services, legal consultation, medical consultation, missing persons inquiries, charity drives, or homework help. These types of posts will be removed.” The rule change is actually best summed up by this line from moderator nunobo: “If you have been stabbed or are bleeding from the head, go to the Emergency Room instead of starting a ‘I am bleeding, what should I do?’ thread.” (/r/AskReddit)

Did I miss something? Let me know in the comments.
