Describing Web 2.0 as the "latest fashion", Mr Nielsen said that many sites paying attention to it were neglecting some of the principles of good design and usability established over the last decade.
Finally an "expert" reaches the right conclusion. However, some things are not right. My dear Mr Nielsen, let me ask you a question. In what way is the web about get in, get in and get out? Clearly this is the way ordinary users who don't understand anyway use the net. But this is not tenable, and any amount of rubbish can be seen when doing this. What the internet is for is information, not misguided entertainment searching. We serious users must protest this rampage.
Web 2 is doomed because lack of information. When Nielsen sees this he will become a real expert and not just some touted guru. Now he speaks some clarity among nonsense, but mostly he is wrong.
