Web 2.0 describes a set of next-generation Internet technologies. These protocols and tools make it easier to create online applications that behave dynamically, much like traditional PC-based software. They're also highly social, encouraging users to manipulate and interact with content in new ways. Web 2.0 pushes computing power off the desktop and onto the Internet, which means less time and money spent on PC software administration. As a general rule, Web 2.0 tools are also less expensive than traditional software — and many are even free. Because they're Web-based, all you need to get started is an up-to-date browser.
