"A 72-hour conversation, the Pitch.
As the web enters its second decade, the old barriers are blurring or
breaking down completely. Media is transforming technology and technology is
transforming media. Web “designers” are starting to write a little code, while
Web “developers” are learning to twiddle pixels. AJAX is redefining the
boundaries between client and server. RSS and web services give you the power to
recreate the web the way you want it.
Everything is getting a little MIXed up. "
