Question #2056

Geek Question of the Day: Reddit has over a million 'subreddits' dedicated to countless topics, but it occurs to me that I've never asked you; What are some of your favorite subreddits and why are they interesting to you? Feel free to post links if it helps! Try and keep it family-friendly but otherwise anything goes. Oh and it's not used much, but there technically is a Geek Questioner subreddit that I slapped together a while back (link below)...
