I've been getting more into #openstreetmap recently thanks to running #osmand on my phone (instead of using the service formerly known as "Don't Be Evil")

#StreetComplete is pretty good for walking around and filling in missing info.

But what if you want something more or bigger?

Today I found #MapRoulette

https://maproulette.org/

There are challenges to update things, fix problems, solve mysteries, etc. And! They give very clear instructions on what to do.

Today I "merged a node and an area" for the first time to make my local ponds be true bodies of water instead of dimensionless points on a #map.
