Starting today, South by Southwest is transitioning over from the Internet and Film festivals to the Music festival, but before we dive in to the 1,500 bands that will begin rocking Austin, we still have a lot of Interactive interviews to share with you.

The Internet darlings of this year's SXSWi is Twitter, a social networking service where you tell your friends what you're doing through SMS, provided by Obvious Corp., San Francisco start-up founded by the inventor of Blogger.com, Ev Williams. But LAist learned here that Ev didn't create Twitter, indeed Jack Dorsey earned that title, so we tried to interview him in the wee hours on the dark streets of the state capitol to humorous results.

The plans went out the window when former Google/Blogger geniuses (who now work at Obvious) Jason Goldman, and Biz Stone jumped into the conversation with Ev and Jack. And to make things really fun, current Googlers Eric Case and Jason Shellen made cameo appearances.

Join us now as we meet the boys who were still aglow from their recent SXSW web award victory for best blog and their product's second birthday.
