I don't have a profile. Myspace either. I understand the appeal of it, make your profile look like you're the most popular social butterfly on the planet even though most people in real life hate your guts. A coping mechanism I suppose.
But there are some downsides. Know why they call it a profile? It's related to Criminal Profiling. You're doing the government's job for them, you fucking idiot! For christ's sake, some people even put their middle initial on these things. Why don't you just volunteer for fingerprinting?
I can see a dystopian society in the future where you have to have one. Just because some insecure bitch wanted to play make-believe. Delete your profile.
