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.
Delivered it deliberately in preparation for a submission (i.e. before we even submitted the talks but knowing full well that that would be the end goal). Both the talk and delivery were engineered with those audiences in mind, so we restricted recording and distribution of the talk at the prior OWASP meetup until after it was published at BH/DC.
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.
