If you need to poll a big group of people, Typeform offers an intuitive interface and a ton of options, all for free.
The de facto free choice for creating web forms and surveys has been Google Docs, but Typeform has a much nicer interface, and a few more options. The survey creator lets you drag and drop 20 different question types, each of which has a ton of options like requiring responses or adding multimedia. Once you’re done, just share the link to your survey, and watch the results roll in on an easy-to-read analysis page.
Typeform is in open beta, and only lets you create three forms with 20 questions and 5,000 responses at first. Sharing a few words about it on a social network though will remove the restrictions.
