From Marketing Voices:

The legendary Guy Kawasaki, entrepreneur, venture capitalist, author and Twitter aficionado talks about the strategies he uses for gaining incredible numbers of people following him on twitter. More than 180,000 people are reading his tweets as of October 2009. He talks about how there is no correct or incorrect way to use Twitter despite the challenging criticisms he gets from his followers on his strategy. He uses Twitter mostly promotionally just to build Alltop, a company he co-founded and loves dearly. Guy talks about how he is a broadcast network—more like PBS– as he educates his readers with his content-rich tweets. He uses ghost writers and discusses his transparency and tricks-of-the-trade.
