Polls.io

neat! reminds me of wedgies. www.wedgies.com

Polls.io is something I worked on with @zacharycollins a couple years ago. It ended up being featured on TNW and numerous education blogs. While neither of us are the current owners of the site, I still think it's a great resource and remains an extremely easy (and free!) way to quickly poll an audience.

I like the simplicity -- no signup required. I created a quick poll: If you were on a desert island and you had only ONE mobile messaging app, which one would it be?
