I would be interested in hearing about other hobbies / interests / past times / etc have decent subreddits (beyond programming / hacking).

My current obsession is skydiving and r/skydiving is a pretty good discussion forum and link aggregator for the topic.

My previous obsession was starcraft 2 and r/starcraft was very interesting to me.

I've juggled for years and occasionally swing by r/juggling and tend to find interesting tid bits.

/r/askhistorians has excellent quality content, potentially the best of the ask* reddits. Mods are brutal about moderation, leading to few but high quality discussions.
