Dean Takahashi reports on the Tim O’Reilly and Jonathan Schwartz Q&A session, detailing everything from “utility computing,” to Sun’s adoption of a “greener infrastructure” and of course Sun’s recent purchase of MySQL.

Schwartz says his top job is being a communicator as CEO. Getting a message across to the troops, who ask him questions like “Why did we spend $1 billion on a company (MySQL) that gives away its products for free?” How does he keep his own voice and PR out of it,” Reilly asked. Schwartz said it did terrify him when his general counsel started blogging.
