Had you presented to the meetup before applying or only after you knew that you were accepted in the conference? Even having done a talk once is far better than most applications.
It didn't go all that smoothly at DEF CON (which I'll freely attribute to us both being conference noobs), but it went pretty well overall, all things considered.
Don't know if we'll have anything interesting to talk about next year, but I'm looking forward to potentially doing it again.
