Now that all the roads are mapped in my area, I was looking into what I could do next when I decided to give StreetComplete a try. It’s a surprising amount of fun that gets me out on my feet for hours joyfully entering attributes for shops, sidewalks, etc. It also seems to be a very easy way for newcomers to participate in a fun and useful kind of way.
I suggest you give it a go, also works on motorcycles and bicycles!
My plan is to organize a Localization hackathon to get StreetComplete translated into Thai, is anyone interested in participating/helping?
