String theory is interesting. I've read Brian Green's books, as well as a few dozen other physics books ranging from the extremely pop-sci standards like The Physics of Star Trek, to the deeper and more philosophical types (a la Roger Penrose -- I really enjoyed Emperor's New Mind), and a couple of solidly text-ish books. The truth is that I am a Physics Groupie, though. I am fascinated and awed by it (and always end up talking physics when drunk), I understand it well enough, but that's where my relationship with physics ends: understanding, not inception, not creativity. Like any good groupie, my job is to stand at the sidelines and get hot and bothered, rather than attempt composing the music myself; I may go as far as to strum a few chords, but that's it. So, while I find the theory interesting, I can't give any really concrete or insightful explanation as to whether it's the most brilliant bit of hypothesizing in the field or folly that should send us all running to the loop quantum gravity team.
Right now I am imagining various physicists in "TEAM STRING THEORY" and "TEAM LOOP QUANTUM GRAVITY" tee shirts which is kind of awesome.
