In 2004, I wrote: “I’m searched, therefore I am. To borrow from Rene Descartes' philosophy, in today's Internet-obsessed world, we know we exist, not because we think, but because we're searched.” Today, thanks to Twitter, it's more like "I'm followed, therefore I am." Indeed, even Twitter CEO and co-founder Jack Dorsey says Twitter essentially captures the "status of everything." Wait, I thought Google was God? Anyway, Jack came to the Vator studio for a three-part interview to talk about Twitter’s business model, the Summize acquisition, the introduction of video updates, and how he views Seesmic, which calls itself a video Twitter, FriendFeed and Twitter clones, such as Pownce, Plurk and Identi.ca. This is the first part.
