Balanced users, those that plant both quick and long time harvest, know when they have the time for it. Facebook applications can help employers to see the 'attitude' of an employee or an applicant when they are on the game applications. Friends would also be able to find how long 'that friend' could be patient! It would also show on how long a user accepts a friend invitation or a gift.
There is a lot to be learned from Facebook about users who are your friends. For most, you will be able to know their likes and dislikes and how they express their emotions. Some people say Facebook applications are kids’ stuff. Well, if they don't know how to look into it - that's the reason they are not at Facebook.
