"Are you ready for the new Web?...Things may look the same as the
old Web, but under the hood there's been some serious tinkering, and after years
of hype among propeller-heads, some of the effects are finally arriving. That was
the big takeaway last week at a conference in San Francisco called Web 2.0. The
idea of the confab was to explore the implications (and, for a number of attending
VCs, to ponder the investment opportunities) of these new layers of technology
and the massive activity on the Web that makes them sing...'Web 1.0 was making
the Internet for people,' said Amazon.com's Jeff Bezos at the conference. 'Web
2.0 is making the Internet better for computers.'"
PC Magazine noted that "The Web glitterati came out for the Web 2.0 conference at San Francisco 's swanky Nikko hotel this week. In attendance were Amazon's Jeff Bezos, Netscape cofounder Marc Andreessen, Bill Gross of Idealab fame, Mark Cuban of HDNet, and many more of the familiar faces that were prominent during the Web-wild 1990s."
