So today on my facebook home page this box with different profile usernames showed up.
As I am not as familiar with FB (or most networking sites/technology in general) I thought I would ask the more FB savvy individuals out there what the point of this was.
1. Do I HAVE to have a FB username?
2. What is the point/benefit to having one?
3. Would I then use that as my login username?
4. Is it better just to stick with you email?
I appreciate your answers, as FB was unable to provide any to me :)
