Facebook Questions is designed for you to get more responses to whatever your burning question is. For example, you are trying to decide where to go on your next vacation and you are debating a few destinations. You could just post the question as a status message but statuses aren't easy to share on Facebook. Ask it in a Facebook Question and it will show up in your friends' news feed and the news feed of their friends for a guaranteed increase in response.
Facebook Questions is also very flexible. Using the where to go on vacation example, you can also have the option of letting people write in additional answers. So if there is someplace one of your friends really think you should go, they aren't limited to just the options you included.
And it is very easy to create a Facebook Question. If you have the Facebook Questions app installed you just have go to the status box on your Facebook page and click on Questions.
So the next time you have a question that you really want your friends to weigh in on, put it in a Facebook Question.
