well he has his own views on the topic but i think that the main thing is what we want form a site. today a visitor on orkut has a lot of time. but if the pages to load slowly he will run away to other SNS site. and also if the working is not easy to understand then also he will get discouraged. after all first impression is the last one.
so i think web 2.0 is suitable for some kind of websites. all websites cant haev the same way of design. like a photogrpaher cannot use web 2.0 sites cause he will have more images and not much text.,
