OpenStreetMap community

I use it via osm directly when available. Others will likely start to develop apps that use such data. Once enough people bother to provide it.

There are many many apps developed specifically to aid disabled people. But as the people using those apps are often the least able to gather the data. It is down to people with more mobility to provide data before it can practically be used by developers.

I do my best when in an area and my vision is more available. Although its always pretty crap. At the better times I can at least tell the surface.

Unfortunately OS data is one of those things. You need the horse before the cart. So it requires people to understand potential uses rather then actual use at the time.

As the idea of the data is to be available to less resourced developers. As well as OS ideals in genral. It is unreasonable to only expect data to be of value if you see a value today.

PS I am in no way suggesting you are wrong for how you choose to use your time. It is yours and its value can onlybe judged by yourself.

I am just trying to point out that the data you see little value in. Can be important to others. Either now for those with some technical inclination. Or in the future if gathered by those willing to consider it.
