It would be cool to offer poll/survey questions in answers.atlassian.com. For example, if I wanted to take a poll to determine the number of Confluence plugin developers there are on answers.atlassian.com vs. others and to determine whether those developers are working for an Atlassian partner organization, contracting on their own, or being paid full-time to work as plugin developers, etc.- that is not a question that I could pose here or on the mailing lists and expect to get the response I would if multiple-choice poll/survey functionality were to be provided.
I see some mention of OSQA thinking about adding it at one point here: http://meta.osqa.net/questions/112/polls-and-surveys
However, I don't know if there was follow-up/if anyone created a module for this. Has Atlassian looked into providing polls/surveys via answers? Maybe it would be a good idea for a ShipIt day?
