The MIT Technology Review article says this about the buzzword "Web 2.0" -
"User-centered Web phenomena such as blogging, community photo-sharing (exemplified by Flickr), collective editing (Wikipedia), and social bookmarking (Delicious), they argue, are disrupting traditional ideas about how software is built and how information is generated, shared, and distributed on the Internet.
With almost half a million Wikipedians contributing and editing articles, 90 million people running the open-source Mozilla Firefox browser, and 18.9 million people now publishing blogs (according to blog search engine Technorati), the case goes, it's hard to dispute that users' attention is gradually shifting away from the products of traditional publishers, media companies, and software makers."
The article also quotes Barry Dillar, CEO of IAC, providing a different opinion,
"There may be audiences of eight to 12 people interested in somebody's individual expressions, and more than that in some cases," Diller replied. "But the truth is, that's where editorship comes in. A process with people who have talent and expertise at making entertainment products is not going to be displaced by 18 million people coming up with their videos that are only entertaining because they're awkward and stupid."
