I mostly visit niche subreddits. I like to get all my software development news from here instead. So I use reddit for whatever other interests I might have at the time. Basically whenever I have a new interest/hobby, I would spend a few days into that specific subreddit and absorb as much of the collected information as possible. These vary a lot so I might subscribe to some subreddits only for a few months and then go on to others.
