It is rare to find a project with such a ridiculously high importance over funding ratio.
They do still seem to have a bit more activity than https://gis.stackexchange.com/questions/tagged/openstreetmap on Stack Exchange.
- Transliteration is off by default!...... https://wiki.openstreetmap.org/wiki/Translation You just have to learn all scripts ever. Good luck with the chinese characters. Genius.
- In order to see information about places, you have to click "Query features" on the toolbar first. Who made such a terrible UI? Direct click is a much, and so easy to implement?
- It is impossible to discern different types of paths and other walking path symbols, the symbols are too small, and just scale down to a line no matter how much you zoom in.
- Power lines are way too visible. While that is kind of cool, it is useless and distracting to most people most of the time.
- No street-level imagery...: https://help.openstreetmap.org/questions/1178/adding-photos
- No aerial imagery: https://help.openstreetmap.org/questions/6849/how-can-i-see-the-aerial-imagery-without-editing-the-map But that is kind of understandable, as that one might not be free.
- No restaurant ratings: https://help.openstreetmap.org/questions/64852/ratings-for-pois because it is "Subjective". OMG those people, such a huge value powerhouse wasted.Not just for restaurants, but for other things as well, e.g. sharing of good cycle circuits.
All of this is a shame, because they do have some incredible data that you cannot find easily on other maps because people just edited it up.
