Ask HN: Can anyone recommend a web-based tool that unlocks simultaneous answers?
One interesting way to go about this would be to maybe have everyone fill out a survey, or write their own little manifesto, and keep the results secret, and then simultaneously reveal everyone's results to everyone else at a pre-determined future date.
The easiest way I can think of to do this would be to just have everyone write a Word/GoogleDoc/Text doc of some kind, and have them literally drag it into a Dropbox/Drive/iCloud folder at the same date and time.
However, I'm wondering if there is a tool out there that would make this more fun, and done in such a way that any individual who just wants to get it done ahead of time can do so, and let the software do the reveal?
Is there any kind of cool, "Simuldrop," tool or method that anyone out there has built or uses? A web-based tool would be cool and have the widest reach, but any suggestions for command-line tools, technical solutions could be interesting as well of course because after all...this is hackernews.
