WEB 3.0

Internet Guru, Jeffrey Zeldman from A list apart wrote an interesting article about the web 2.0 buzz. He's negative towards the web 2.0, I hate to come to the conclusion that he has a few good points. His last paragraph is not really motivating:
To you who are toiling over an AJAX- and Ruby-powered social software product, good luck, God bless, and have fun. Remember that 20 other people are working on the same idea. So keep it simple, and ship it before they do, and maintain your sense of humor whether you get rich or go broke. Especially if you get rich. Nothing is more unsightly than a solemn multi-millionaire.
In the comments on Jeffreys' article, some interesting points are made. They explain my feeling about the article, I'll quote some here: This is a reaction on the anti-AJAX part in the article:
Keep it simple.
  1. Web sites can be made much better for the user with the principle known as AJAX.
  2. Be sane about your usage of AJAX
This reaction was my favorite, I couldn't have said it better:
While I tend to agree with many of the points made here (especially the bit about Ajax being a bitch to wireframe, ain’t that the truth) I can’t help but feel a bit frustrated that: A) It has to be said at all. B) It takes someone like Zeldman to get this stuff to sink in. C) In a way it’s just more spin. Web 2.0, Web 3.0, etc. It’s not the numbers that matter. It’s all “Web” and this stuff should be about people not technology. A successful Web application can be built with Ajax, or not. It can rock on Ruby on Rails or be a bit slower on PHP and be a great app either way. Ultimately I feel this kind of hype doesn’t matter much at all and it’s kind of crazy there is so much time, effort and brain power spent debating about it. But, hey, it was a fun read.
All I can add to this, is that I like working with the new "web 2.0" applications, I like flickr, del.icio.us, ... I like interacting with people on flickr, it's more fun than having a discussion on a phpBB forum. Just because the user experience is better, not because it is a WEB 2.0 application. Last week during my presentation of my thesis subject. One of my lectures asked me: "What is the WEB 2.0? Isn't it nothing more then a hype?" I hated that question, I wouldn't have tought that I had to explain the true existence of the WEB 2.0. But it was a good question, because it kept me critical. I have to admit, it was pretty difficult to come up with an explanation that really made it sound great. As a user of a lot of WEB 2.0 apps it's sometimes difficult to stay objective. These kind of articles and critical teachers really help keeping your realistic view on things. It's like in politics, you have a left and a right wing, they have to find a balance.
