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 there was some way for the app to create teams trying to fill out details like in Pokemon Go, that would be crazy exciting. Would be difficult to balance that so it didn’t incentivize adding junk… Maybe having a third party keeping players in check? Not sure, but the possibility is tantalizing!
