Indeed, Web 2.0 is a buzzword now. But what in the world is it & why do we need it ??
First thing first, its not just a one-off technology available of the shelf or downloadable, its just a tech movement.
Who is the world is running this movement?Run by massive participation of free minded people. It just exploded on its own & there was no one telling you about it. Its just exciting + free + accessible.
It was termed by few Open Source guys & it just became popular.
It doesn't have a business model & that is a business-mdel. Its just an innovation & so it does not have to have a business model.
Web 2.0 features Google AdSense, Flickr, BitTorrent, Napster, Wikipedia, blogging, services, syndication & much more. And Google has become a standard bearer for Web 2.0 as Netscape was a standard for Web 1.0.
Great work guys..
