Something I didn't say last time about that one app that I should have:
You're an exceptionally talented, exceptionally interesting young man. But you reveal nothing about yourself until you've been directly questioned. Then you're cautiously enthusiastic about the stuff you're, like, really good at.
You know what's sexy as all hell? Enthusiasm. The unbridled confidence to not just believe but to know that the stuff you think is cool IS cool and that anybody would be delighted to get a glimpse into this awesome world you live in. Passion and enthusiasm is what makes things interesting; being the vessel of that passion and enthusiasm is what makes you interesting.
You're a great communicator. Every interaction you have with a girl should take the form of "you're going to think this is cool because X." If you can make someone feel the awesome you do they will view you as awesome through simple transference.
