Innovation was certainly on display at this week’s Google Buzz press conference, but there was only one moment that truly registered an 9.5 on my personal Coolness Quotient meter. That was during the mobile segment of the demonstration. Vice President of Engineering Vic Gundotra spoke into his Android phone, and the magic of Google Voice, combined with GPS-tagging and location-based services, allowed him to post his “buzz.” I know that reads like something Jeff Spicoli of “Fast Times at Ridgemont High” might have said.
