What's so wrong with an open-source program to help people become "Less Awkward"?

Learning new stuff often involves making mistakes until one gets it right. I imagine that if this community was created, many posts would be of the form "I did X recently and it went wrong; what could I have done better?"

Making mistakes in social situations is something that many find embarrassing, so they might want any such field reports not to become public knowledge. Hence, confidentiality may be necessary for people to talk openly.
