This was on my reading list for a while and I finally got to it today!
"UAS does not have this organic feedback mechanism."
I 100% agree and was disappointed when our SDK was available in UAS because people would downvote and comment things like "this is broken" not realizing there might have been a recent update or breaking change that might change how they were (or are) trying to use it. We had no really good way of showing the changelog and indicating what comments were known bugs or user issues.
We moved off UAS and are on GitHub which I think is a more natural fit, given that its an open source project. But I think we've lost some of the ease of use by not being in the UAS.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
