5. Barack Obama

why on earth does the most powerful man in the world need a twitter? even so, i expected to read some pretty badass tweets about negotiating with enemies or straight up kicking their asses. instead, this twitter page is like a live stream of c-span.
"The President will deliver remarks on new auto emission and efficiency standards at 12:15 ET. Watch the live stream: http://bit.ly/19qtmw"
who gives a shit? and to think - some asshole is getting paid with our tax dollars to tweet this baloney (bologna?).
4. Oprah

"Why I LOVED today's show: puppies get saved. Prisoners get healed. Soldiers get helped. Full circle blessing. Thanks for watching."
we get it oprah, you're awesome. as if you're magazine, television show, and books aren't enough - we don't need to read about your self-proclaimed miracles on twitter.
3. Ellen

"My outdoor show is today! Only watch it if you wanna see:No Doubt perform their greatest hits, George Lopez get bleeped & lots of ice cream!"
no, no, and no thanks. ellen's cheesy sense of humor does nothing but scare me. she come's off as a happy-go-lucky-closet-jeffery-daumert (the serial killer). i can't believe they gave her a tv show, let alone a twitter page.
2. Dave Matthews

"It's crowded in here. Not really. Lotsa room. I've been drawing drawing drawing drawing. What about you?I am a rabbit/donkey/monkey/man."
if you thought his song lyrics were deep, his tweets are even deeper.
1. Paris Hilton

"At my party at Club VIP! So amaazinggggg!!!! Huuuugeee"
"Laying out by the pool at Hotel Du Cap. Its so beautiful out! Loves it! Huge!"
i could go on forever about how dumb this broad is, but i will leave that up to your own personal judgement:
