the only piece of evidence i'll ever need to prove that twitter is mostly used by tweens & that the parents of tweens rule the economic world:
justin bieber and/or #happy birthday justin are trending topics today and most other days.
i'm not even a 100% sure of what a justin bieber actually is, although it does not sound interesting. is it a new species of marine sealife?
additional supporting evidence of tween world domination (not that it's necessary):
miley cyrus and the jonas brothers both earned over $25m in 2009 alone.
w.t.f.
