Facebook's adding a Questions service on the social network. They found that a lot of users were asking their friends, in their status updates, for opinions (such as “What's a good restaurant to eat at in LA”) or even just information about themselves (such as, “What pet did you have growing up”). Friends would reply by commenting on such statuses. Facebook wanted to make this interaction more useful and began experimenting with Questions.
Get your questions answered
Through Questions, they want to make questions faster and easier to answer. The service will let you answer a question with either a single click to an existing answer, or you can add your own answer to the mix. This works in two ways, one, it's faster for people to answer, two, it helps to see what the popular choices are. When one of your friends answers a question you posted, their friends can see it too and can choose to answer. This is supposed to cast a wider net. For out of the ordinary questions, you can open up the question to a broader group, but Facebook will filter it to show you your friends' responses before non-friends'. By clicking on 'others', you'll be able to see what the non-friends say.
