"Google happens in the space between browser and search engine and destination content server, as an enabler or middleman between the user and his or her online experience."
"While both Netscape and Google could be described as software companies, it's clear that Netscape belonged to the same software world as Lotus, Microsoft, Oracle, SAP, and other companies that got their start in the 1980's software revolution, while Google's fellows are other internet applications like eBay, Amazon, Napster, and yes, DoubleClick and Akamai."
"Napster (though shut down for legal reasons) built its network not by building a centralized song database, but by architecting a system in such a way that every downloader also became a server, and thus grew the network."
Harnessing Collective Intelligence
"Hyperlinking is the foundation of the web. As users add new content, and new sites, it is bound in to the structure of the web by other users discovering the content and linking to it...the web of connections grows organically as an output of the collective activity of all web users."
"Their adoption is driven by "viral marketing"--that is, recommendations propagating directly from one user to another. You can almost make the case that if a site or product relies on advertising to get the word out, it isn't Web 2.0."
RSS & Web 2.0
"It may seem like a trivial piece of functionality now, but it was effectively the device that turned weblogs from an ease-of-publishing phenomenon into a conversational mess of overlapping communities."
"Discussion emerged. Chat emerged. And - as a result - friendships emerged or became more entrenched."
"It may not reflect the deep structure of the brain, which is often unconscious, but is instead the equivalent of conscious thought. And as a reflection of conscious thought and attention, the blogosphere has begun to have a powerful effect."
"Second, because the blogging community is so highly self-referential, bloggers paying attention to other bloggers magnifies their visibility and power. The "echo chamber" that critics decry is also an amplifier."
"The world of Web 2.0 is also the world of what Dan Gillmor calls "we, the media," a world in which "the former audience", not a few people in a back room, decides what's important."
"Imagine if MapQuest had done the same thing, harnessing their users to annotate maps and directions, adding layers of value. It would have been much more difficult for competitors to enter the market just by licensing the base data."
"In others, the winner will be the company that first reaches critical mass via user aggregation, and turns that aggregated data into a system service."
"Users must be treated as co-developers"
"Think syndication, not coordination. Simple web services, like RSS and REST-based web services, are about syndicating data outwards, not controlling what happens when it gets to the other end of the connection."
"iTunes and TiVo also demonstrate many of the other core principles of Web 2.0. They are not web applications per se, but they leverage the power of the web platform, making it a seamless, almost invisible part of their infrastructure. Data management is most clearly the heart of their offering."
"A Web 2.0 word processor would support wiki-style collaborative editing, not just standalone documents."
