I mentioned your post to a couple of people online who I found to be in the most dire need of a similar action, and their reaction was a complete misunderstanding and rejection. Here is the anonymized quote:

wtf is this s**t

his solution is "learn to be good at reading body language and reactions, find a group you have common interests with and interact with them a ton, get useful feedback from your social partners"

if I could do any of those i wouldn't have a problem

not to mention that his entire post is just a fucking humblebrag

"I'm so smart and good at deep thought others can't follow/remembering more about their lives than they do that everyone hates me"

So, unsurprisingly, the people most in need are the least likely to benefit. For the same reason you did not find the neurotypical feedback useful. The spectrum is wide and multi-dimensional, and those far from the center are not necessarily close to each other.
