r/askhistorians is pure gold. Hobbyist subreddits are extremely valuable - discussions are polite, to the point, high-quality posts get consistently upvoted. r/coronavirus and r/COVID19 have been pivotal in making sense of the situation in early March (though r/coronavirus turned into a parody of the former self once Covid started spreading in the US). r/nottheonion or r/gaming are often hilarious.
There are three important steps to turn Reddit into a useful tool:
- Unsubscribe from the subreddits you find toxic
- Learn to use 'Sort by Top - this week/day'
- On PC, visit old.reddit.com instead of reddit.com. On mobile, use a third-party client like RedReader or Appolo
