Sending out survey is so last season. What you really want to know is - do you like or not? IdeaScale can do that for you. It's like getting a bunch of people in a room and getting a bunch of thumbs up or thumbs down. It's great! Now, it is not totally easy - you need to do a little homework, market it and make it super intuitive for your target audience.
Can you do it? Go check out IdeaScale.com.
