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.
if they changed it at some day, maybe the change wasn’t updated in f-droid afterwards. anyway, my osm account was “empty” before, because i just didn’t manage to finish my first map update try (which was in 2012 o_O ) now i’ll try again and thus they get a trust advantage based on doing good and it looks easy. trust advantage until i read or experience something bad of course, but i’ll try it these days.
