Well, based on my favorite subreddits, let's see:

/r/starcraft: doesn't have nearly as much good discussion as TeamLiquid, but TL's forums are not easy to trawl through. Great coverage of tournaments/announcements tho

/r/personalfinance: really great here, lot of professional financial experts drop knowledge bombs. I've improved my financial life oodles just reading through this.

/r/piano: lots of great/interesting posts, mostly people playing pieces or shots of their set-ups, not too much memery but people try a little bit. Quite a few better/more experienced players than I am to answer my Q's.

The main thing I hate is memes. They are very low effort, many of them are inside jokes/highly meta, and the humor is usually bargain-basement, not very funny. If you can avoid those subreddits where memery takes over, then you have a better experience IMO.
