As you mention in your second footnote, the idea of a 'pickup artist' carries unfortunate connotations. I'd suggest you change your headline to something that you won't have to explain "it's not really what you thought when you first heard it".

Perhaps "Optimizing interaction techniques for social enjoyment"? This has the benefit that while the pickup artist is perceived as interested in social engagement as a means to orgasm, practitioners of the techniques you discuss would be perceived as interested in social engagement as an end in itself.
