Web 2.0
For long I didn't understand Web 2.0. Then I read Kiruba's article in Business Standard. I am convinced now that Web 2.0 is pure alchemy. You create data from non existent sources.
With Web 2.0 type sites, it is possible to combine data from various sources, even sources that you don't own control or even exist, and turn that into data that people can use.
I am enlightened.
