Four simple polls:
I welcome comments on:
(a) how many proposals you submit per year
(b) anecdotes on the highest number of attempts you have ever heard people make, typical practices in your field, etc.
(c) how helpful your program officers are in helping you rework the proposal and eventually get funded
(d) whether you feel that the response to one panel actually improves your odds with the next one
(e) whether you include a response to panel comments when you resubmit (if so, body of proposal or supplementary docs) and whether it the norm in your directorate (anecdotally we know that in some it is, in some not)
Anything else that comes to mind regarding your NSF experiences!
