Pawel Szczesny had a great idea about visualizing Science 2.0, Health 2.0 and Culture 2.0:

Initially I had an idea to launch a huge portal around “2.0″ meme – essentially tracking changes in communication methods across various areas. I wanted to quit science and start a consulting career in helping people to communicate more efficiently (new channels and tools, efficient visual communication, etc.).

Later he created AllTwoPointZero.com,

Even if the “2.0″ phenomena are not a future anymore, “2.0″ is still a useful meme to attach to processes of change. This site is a simple tracker of the news and discussions on a few aspects of the “change” that happens because of the internet. In its current form its not even beta – treat it as experimental alpha, with more links and sources to come.
