What is this thing called Web 2.0?

Tim O'Reilly wrote a piece on web 2.0 in 2005 that is illustrated by this mindmap created by Markus Angermeier.  Read Tim's article

You will keep seeing this term "Web 2.0" but finding a clear definition of what it is or will be is tough. Easy answer: it is what the web is becoming and (unlike Web 1.2 or whatever might have been the next version) it will be significantly different from the web we know & use today.

In this second version of the web, the architecture and the applications of the web will change.

1) This web will be interactive beyond clicking links on a page. I believe many applications will be running online, data files will be stored online "in the cloud."

2) Collaboration will be recorded in this space too. This is the web as operating system or platform.

2) This new web will require new security functions that had not been really considered in 1.0 (though that's what we should have expected and I don't blame Sir Tim Berners-Lee).

3) Web 1.0 encouraged sharing and stealing of content. 2.0 will further all of that. I don't mean to say that is a good thing. It's a social aspect that will require changes in our definitions of terms like sharing, plagiarism, fair use, copyright, ownership in the private, commercial and legal worlds.

4) New economic models will emerge of how to use this web for commercial moneymaking purposes. Web 1.0 never saw that. Now it's obvious.

5) Internet2 is an attempt to create another web for education and research use, but the other players will also want that speed and be willing to pay for it. If they stay separated, the "commodity" internet may end up being faster, stronger and more cutting edge then the research web. As with most technology in education from K to 20, education will be playing with the old toys.
