This is a question that I've been thinking about for a long time now.
I used to be more active in pick-up artist (PUA) communities in the past, and I was even close to saving money for one of their ridiculously expensive workshops. I have since removed myself from this crowd, but I always wondered if the workshops and associated materials were truly effective. I have two DVDs (one of which my friend gave to me, which I have given away to someone else), but I always felt that the "basic" material was simply a re-hashing of the fundamentals of social dynamics, which are sound but hardly worth the cost of entry. (Some workshops are near $4,000.)
Has anyone here tried it or still participates? What are your opinions?
