I first learned of Street-Complete here and I really like it.
It’s satisfying to walk around, complete little tasks, and get prizes, scratching a similar itch to Pokemon Go.
Stuck waiting for someone? Add opening hours for a few local businesses.
Have a long walk ahead of you? See if you can add/check house addresses as fast as you can walk.
Want to walk off a few beers before heading home? Complete some tasks in the bar street.
Its a very constructive way to “be right” on the internet.
Friendly PSA that there is also StreetComplete ExpertEdition (on F-Droid only) which as more tasks and crucially allows you to directly edit tags. Very recommended if you know what you’re doing and have some more familiarity with OSM.

Oh, this is interesting. I’m not the most advanced OSM user, but I’ll definitely take a look at this and learn.
