Search-engine advertising — where companies pay to have their Web site displayed on search-engine results — has been big for several years. But now companies can target their ads within the context of what people are reading online.
Tim and other web analysts, a good Web 2.0 site should :
provide services, not just a packaged software, and ensure cost-effective scalability,
be based on unique and hard-to-recreate data sources that get richer as more people use them,
trust users as co-developers,
harness collective intelligence,
leverage the long tail through customer self-service,
be potentially deployable on any device,
provide users with lightweight user interfaces, development models, and business models.
The criticism exists that "Web 2.0" does not represent a new version of the World Wide Web at all, Amazon.com , for instance, has allowed users to write reviews and consumer guides since its launch in
criticism has included the term “a second bubble” (referring to the Dot-com bubble of circa 1995–2001), suggesting that too many Web 2.0 companies attempt to develop the same product with a lack of business models.
Critics have cited the language used to describe the hype cycle of Web 2.0 as an example of Techno-utopianist rhetoric.
Critics such as Andrew Keen argue that Web 2.0 has created a cult of digital narcissism and amateurism
