Web 2.0

as defined in wikipedia;
Web 2.0 is a trend in World Wide Web technology, and web design, a second generation of web-based communities and hosted services such as social-networking sites, wikis, blogs, and folksonomies, which aim to facilitate creativity, collaboration, and sharing among users.
basically, web 2.0 is how the internet is developing, to accommodate more user-generated content. social networking sites, where a user can edit their profile to represent themselves, whilst interacting with others, such as myspace, is a prime example of web 2.0 technology.
although web 2.0, a term coined by O'Reilly media, is not so much a technology as an idea behind the technology, it is a rapidly expanding aspect of the internet.
