Ask HN: Is there a place to submit early stage market surveys?

The reasoning is: There are places to submit your already built or in alpha/beta tech products (betalist, startuplist, etc), crowdfund your physical products (kickstarter, indiegogo, etc), but is there a place to submit your "Market surveys" for apps/ideas before they even begin to be built?

Besides mturk, spamming your friends, mailing lists, etc.

Thanks HN!
