Web 2.0 is a collection of browser-based Internet technologies that enables anyone with an inexpensive computer and a decent network connection to join what the author calls the Internet Commons - a place where users can create elaborate multimedia expressions of their thoughts, opinions, and feelings, as well as link to and comment on those creations. Mobile 2.0 is being heralded as a successor to Web 2.0, extending its capabilities to mobile devices while coping with their limitations and leveraging the opportunities of location-based computing.
