Cisco is all about Web 2.0., so with that in mind, I attended an “Book Club” interview yesterday at Outcast Communications between Michael Arrington of TechCrunch and Sarah Lacy. They were talking about Sarah’s new book (to be released today), “Once You’re Lucky, Twice You’re Good” which grew out of Sarah’s BusinessWeek cover story of Digg’s Kevin Rose in August of 2006. The sub-head of the book is “The rebirth of Silicon Valley and the Rise of Web 2.0.” While I might argue that with Cisco, Intel, HP, Genentech, Sun, Google, eBay, Adobe, Apple, Oracle, Symantec, Verisign, Yahoo! and many others that a few start-ups don’t define a Silicon Valley rebirthing, I look forward to reading the book and her point of view.Her book “is the story of the entrepreneurs who learned their lesson from the bust and in recent years have created groundbreaking new Web companies. The second iteration of the dotcoms-dubbed Web 2.0-is all about bringing people together. Social networking sites such as Facebook and MySpace unite friends online; YouTube lets anyone posts videos for the world to see; Digg.com allows Internet users to vote on the most relevant news of the day; Six Apart sells software that enables bloggers to post their viewpoints online; and Slide helps people customize their virtual selves.”I got a copy of the book last night (thanks for signing it, Sarah) and haven’t read it yet, but will and will offer a review on this site asap.Note: If you’d like to see (and kind of hear) the Arrington/Lacy interview, you can do so on TechCrunch site via Qik. Qik allows you to stream live videos from your phone, so the sound quality without external mics is a bit iffy, but still a pretty cool technology.
