Then their eighteen year old brother will flick them in the ear and call them a loser and a noob and they'll quickly learn.

Lucky teenagers don't revolt anything their older peers tell them as fact ;)

When you were 12 years old, did you go out of your way to tell your parents/brother that you had a myspace?

MySpace was an exclusive club for "99-year old girls" to fawn over their favorite bands, or for older boys boys to post pictures of "hot babes" to impress others in their age group.

I'm not sure it ever matured from there.

That seems like a problem too, though.
