Guy Kawasaki on "Use Twitter as a Marketing Weapon"

I'm new @Twitter. So once that i'm not interested on write about how the sun is shinning and the sky is blue, i decided to search what those that I follow have to say about this social media, and i've found a very amazing webinar from Guy Kawasaki... for free! So if you are interested just check it here. And if you want to know more about Guy's, which i highly advice, take a look at his company Alltop. It's worth it! A lot!
