How will Twitter make money? Biz Stone, co-founder, responds...

Although it's an hour-long lecture by Biz Stone (first he co-founds Blogger and then Twitter!) and dates back to the 15th of November last year, this video really is fascinating and a must watch for anyone interested in Twitter. Stone discusses possible revenue sources and monetisation strategies for the platform, which includes the on and off again rumour of charging business users for the service. All I can say is blurry lines... blurry lines. Oh, and of course you don't need to sit here on my blog watching -- feel free to check it out at the Haas School of Business Channel.
