This is something I see pretty often. I'm a business co-founder, so this stuff is pretty much my bread and butter.

An idea I've been kicking around is some kind of "Social Skills Primer" type product, probably done by video for ease of explanation and to capture/explain nuance.

I haven't fully decided on doing this yet, but would that be interesting to you, do you think?

As a side note, I would highly recommend reading How to Win Friends and Influence People.
