Today, Michael posted a link to a Canadian blog who described one of the reasons that Web 3.0 will fail. I agree that greed and closed systems will cause the downfall of what has been coined as “Web 3.0″.
There’s a more fundamental reason, though. “Web 2.0,” as a term, was coined after the movement was already… well… in motion. The public started responding to certain types of websites. Those websites had certain similarities. They were successful (some of them anyway) because they responded to what excited people.
To quote the Wikipedia entry, Web 3.0 has been described as “the evolution of Web usage and interaction that includes transforming the Web into a database.” I could be wrong, but I don’t think that databases are the most exciting thing in the world to your average web user.
Open message to the web: Stop trying to define the future of the web. You don’t know where the natural evolution will take it. Instead, try making the current web a better place for everyone.
