One big thing I'm seeing with openers is their potential overuse. Clearly there are used because they do work, but it's crazy how many times some lines were used on the PUA show and the worst would be using it on a girl and she'd already heard it before. Recently I was thinking about another direction. As openers, I was thinking about gleaning the current news and bits of weird trivia (such as "do you know where the phrase 'ok' comes from?" or "do you know why a 'sub' sandwich is called that?") to open sets. Thoughts?
