What is Web 2.0

Other people insist that Web 2.0 is a reality. In brief, the characteristics of Web 2.0 include:

• The ability for visitors to make changes to Web pages: Amazon allows visitors to post product reviews. Using an online form, a visitor can add information to Amazon's pages that future visitors will be able to read.
• Using Web pages to link people to other users: Social networking sites like Facebook and MySpace are popular in part because they make it easy for users to find each other and keep in touch.
• Fast and efficient ways to share content: YouTube is the perfect example. A YouTube member can create a video and upload it to the site for others to watch in less than an hour.
• New ways to get information: Today, Internet surfers can subscribe to a Web page's Really Simple Syndication (RSS) feeds and receive notifications of that Web page's updates as long as they maintain an Internet connection.
• Expanding access to the Internet beyond the computer: Many people access the Internet through devices like cell phones or video game consoles; before long, some experts expect that consumers will access the Internet through television sets and other devices.
