My relationship with reddit is mostly just finding new subreddits to 'exhaust' by sorting by top of all time and working my way down a few pages. To feed my addiction to general, non-specific Internet content, I have Metafilter, Hacker News & Designer News (non-industry specific gems show up a lot), and Longform. Also seconding podcasts. Reply All (and TL;DR), Question of the Day, and Note to Self episodes just feel like good Internet posts in audio form.
Thanks for this reminder. I used to hit the random button on reddit to find new subs that might interest me. Once when I did this, I found a subreddit for a hobby I had forgotten about and renewed my interest. After seeing your comments, I hit the random button again and found something else that interested me. It's amazing to see the variety there and the fun new (and old) finds.
