Most (sane) people have already. I think still using Facebook tells a lot about you, none of it positive.
The reason I use Facebook is because it's clear off privacy-crazy "i know better than you" neckbeards. Not using Facebook while being computer literate tells a lot about you, none of it positive. Let me be clear: No, I don't care if my software is free. No, I don't care if Facebook sells the data I upload. Because the benefit of having software that works and connecting with friends respectively is higher than any small price.
