Info on your lookup

My friend put heaps of info about herself on her lookup. She then said that heaps more people became friends with her. Do you think I should put my info on my lookup?

Okay, you can put info on but dont EVER put any info on where you live or your phone numbers or what school you go to or your last name...If you dont put info like that on then your totally good..

Ummm...I dont know what lookup is but what kind of info are you talking about?

*Sigh*.
Info about me.
Lookup being profile thingy.
