informal survey -- have you submitted a talk to nanog & been refused?

i'm trying to understand the supposed dearth of submissions, but i've never been on the programme committee and so i need some data. if you've submitted a paper to nanog that was refused -- ever! -- and are willing to share details (ideally including the reasons you were given for the refusal, and what you were asked to do to fix them, and what you actually did) please send me e-mail.
