Web 2.0 is characterized by increased participation and interaction on the internet through user-generated content and real-time data collection from various sensors. It has grown exponentially from its origins in the early 2000s as the need for more collaborative and conversational online experiences increased. Key aspects of Web 2.0 include social media platforms, user contributions, tagging, and multimedia content like blogs, podcasts, and videos.

2. Web 2.0 is BIG
A Quote from the Web2.0 Summit
“Collective intelligence applications are no longer being driven solely by
humans typing on keyboards but, increasingly, by sensors. Our phones
and cameras are being turned into eyes and ears for applications;
motion and location sensors tell where we are, what we’re looking at,
and how fast we’re moving. Data is being collected, presented, and
acted upon in real time. The scale of participation has increased by
orders of magnitude. With more users and sensors feeding more
applications and platforms, developers are able to tackle serious real-
world problems. As a result, the Web opportunity is no longer growing
arithmetically; it’s growing exponentially.”
