However, when celebrities tweet, most notably comedians...I will follow that.
My two favorites of the moment are:
The amazing and adorable Mindy Kaling:

For those not in the know, Mindy stars, writes and executive produces The US Office. She is amazing. Every Kelly scene has me peeing my pants. And her twitter is unbelievable. She brings the funny. I think I have a crush on her. Some hilarious tweets include:
"You know when all your best friends are in NYC without you having fun and you hope the Cloverfield monster strikes?"
"In the world where ratty underpants are valued, I am King."
"I say, if you love something, set it in a small cage and pester and smother it with love until it either loves you back or dies."
"If Prince William doesn't choose Kate Middleton I'm going to boycott England forever"
"The temptation to end every script I write with the main character "waking up and it was all a dream" is so strong"
And the sly and handsome Aziz Ansari:

This dude is always the funniest thing in anything he does. Tiny bit parts (ala Funny People), and he totally steals the show. Currently on Parks & Rec with my other girl crush, Amy Poehler. His twitter is full of good band recommendations and funny shout outs to fellow comedians.
The best is when they twitter at each other. Hilarity ensues.
