There are two question and answer type facebook applications out there that are almost exactly the same except for small differences.

"Questions" and "My Questions" are apps that users can add to their profile and invite their friends within their networks to answer.

I like My Questions for the fact that it displays a more appealing box in the middle of your profile with your friends' answers to your question. My Questions also has more users at the moment.

Questions is different in that it display a little box on the lower left hand side with your friends' answsers to your question. I do like the Questions home page just a bit more for the fact that it displays a little feed of your friends' questions. You are only able to see the answers to their if you click on the feed link.

A major complaint among users is that as soon as you ask a new quesiton your old question and answers are deleted. There is no history or archive. Another problem is that in order to get to the questions homepage you have to click "edit preferences", which is a bit confusing.
