Tim Berners-Lee, the inventor of the World Wide Web, describes Web 2.0 as the idea of the Web being an interactive space where people can collaborate. An example is provided of using the Diigo tool to annotate and bookmark a news article, then blog about it by converting highlights to quotes and including a link. Key characteristics of Web 2.0 include users owning and controlling their own data, and applications that encourage participation and value-adding by users through rich interactive interfaces. However, some criticize that Web 2.0 lacks clear standards and definitions, and that many aspects like user reviews, syndication, and older technologies predate the term Web 2.0.

- 2. Tim Berner Lee’s thoughts Tim Berner Lee – Inventor of the Internet says Web 2.0 is nothing more than a jargon “ The idea of the Web as interaction between people is really what the Web is. That was what it was designed to be - as a collaborative space where people can intreract. ”
- 4. An example of Web 2.0 I used diigo this morning to annotate a newspaper article about students repeating grades in school. It was pretty neat. I highlighted key parts of the text with the highlighter tool, and bookmarked it. I selected some text in the article and had diigo search for that text on google. When I was done, I blogged it over at Inquiry, using diigo’s blogging tool, which converted all my highlighted text to blockquotes, and included a link to the article for me. I also like, that if I wanted to, I could have posted it to more than one blog simultaneously. I find it pretty easy to use and I will definitely attempt to try and introduce my students to this tool, when my seniors do their research papers.
