DJ, Turntablist, Owner of Fool's Gold Records
Former world champion turntablist turned Kanye West tour DJ turned record label owner and Grammy nominated producer/DJ, A-Trak (a.k.a. Alain Macklovitch) travels the world playing clubs and festivals while on a series of madcap adventures -- including his current search for Europe's best ketchup -- all documented in the tweets. And the Instagrams.
Besides cluing in his fans to his creative progress with infrequent studio updates, Mr. Mandy Moore is adept at culling bits of political humor (a Sarah Palin satire account is one of his faves) as well as re-tweeting anything having to do with cats. At 37, Adams has accepted the age of memes wholeheartedly.
Business Development, OpenX
Tweets tips and case studies on effective marketing in the social and digital space -- everything from how to look great in a Web video to explaining how Sony uses Pinterest to drive traffic.

Business Development, Twitter
If you want to know what's going on at Twitter, here's a good place to start. Former CAA agent and BD executive who set up original web video deals like Joss Whedon's "Dr. Horrible's Sing-Along Blog" dispenses spot-on sports commentary (and retweets) and celebrates bacon with carnivorous glee.
His Twitter bio describes him appropriately as "musicman." The Latin Grammy Award-winning producer/composer has worked with some of the industry's biggest names, such as Alejandro Fernandez, Paulina Rubio and Natalia Lafourcade. His Twitter feed serves up insights from around the music business.
Vice President, Music, Shine America

Sir Lucious Left Foot tweets from his headquarters in Stankonia, Ga., where he asks for input from fans on everything from gun control to sex on the first date to racial politics. Sample tweet: "The name of the group is OUTKAST for a reason, Never wanted to be a part of the Herd."
Songwriter, Record Producer
The pop impresario behind hits by Katy Perry, Maroon 5 and Gym Class Heroes is as off-the-cuff on Twitter as he is careful in crafting radio hooks. Nestled in between "Old School" quotes and a stream of social narration begging to be turned into an HBO series are songwriting tips like "Whenever writing a song and u at a loss for words just chuck in a line about throwin ur hands in the air or sky."
