Frustrated by a term that doesn't seem to mean anything but that all the techies are using? Lee, over at Headshift, gives a decent description of What is Web 2.0? by talking about how others talk about it.
The phrase Web 2.0 is bubblicious right now, with both Business Week and the Economist dedicating some intelligent coverage to its various manifestations in recent weeks. Elsewhere, I notice 198 occurrences of the term in my RSS news reader, which means that lots of people are talking about it.
I particularly like that he provides a range of descriptions, which helps me narrow down the descriptions others use. My take? "Web 2.0" is a term used to refer to everything that is new on the web these days, with a particular emphasis on tools and gadgets that one can customize or add to.
