Reddit has worked around their lack of it to some degree with location-based subreddits like r/AtlFilmmakers. But subreddits are high maintenance, and they isolate content. Plus, the naming conventions aren't standard. Maybe there's r/AtlFilmmakers for filmmakers in Atlanta, but another subreddit for musicians uses the state in the name instead of a city.
It's a bit like folders vs. tags. It would be nicer to have a single filmmaking subreddit with the option to filter on users' locations -- and default filtering out of location-specific posts in other places.
That wouldn't just make for better dating, though it probably would compared to something like Tinder. It could also lead to stronger local communities and better health outcomes.
