Back in December of 2006, Irina Slutsky and Eddie Codel took a trip to South Park in San Francisco, the local web 2.0 playground, to visit the offices of Twitter, which then was called Obvious. Obvious is formerly the company behind Twitter and Odeo. In this LunchMeet segment, we speak with Evan Williams, Biz Stone and Jack Dorsey about Twitter, their new “present tense” blogging tool that is accessible via mobile, instant messenger and web browser. Web 2.0 and community principles at its core, Twitter is fast growing a passionate following. Four years later and that's understatement!
