Hugh Ristik, who was linked in the article, addresses the question of how to generate good pickup advice:
Feminists tend to criticize male sexual behavior and only explain what not to do. PUAs are exploring what to do. If feminists want to guide the expression of male sexuality in ways other than shouting “don’ts” from the peanut gallery, then they would do well to study the teachings of the seduction community, take from it what they like, and throw away the rest.
That doesn't seem to be about generating new advice. Basically he proposes to take someone else's hard-won research, throw away the parts you don't like (with no way of knowing if these parts were important to the function), and repackage it as your own. I'm not sure you can get a superior product that way.
Clarisse Thorn recently posted a useful article about Ethical Pick-Up Artistry, bringing up a few basic critiques of traditional PUA and suggesting a few alternatives.
A proposal to formalize thisNot the same thing, but a discussion on forming a community to practice social artistry in general has been brought up on LW before, but I'm not personally aware of anything coming out of that.
