My biggest wish is that there's an easy way to contribute images to wikimedia and to link them easily with osm. As soon as that's possible, we'll map the world much quicker and more reliable. Someone might take pictures of benches and another one will add the info if there's a backrest from home.
It does exist another working open source alternative, Mangrove Reviews https://mangrove.reviews/ I think it would be good at least to focus on developing and maintaining one.
Great! Thanks!
