Feld expressed his dislike to those fashion words in his famous blog:
I’m personally going to boycott the phrase “Web 3.0” since “Web 2.0” makes me tired enough. There have been some great quips going around the system about this, including Gordon Weakliem’s “I haven’t even gotten around to upgrading to Web 1.0 Service Pack 2”, Michael Parekh’s “Web 2007 versions”, Peter Rip’s “Web 2.0 + 1”, and Nick Bradbury’s “Web 3.0 Does Not Validate.” While I recognize the inevitability of the newest increment of the Web x.0 label, I don’t have to like it.
My points is that they are interesting stuff. Some guys like to use fashion words to attract eyeballs. As long as they can illustrate the essential points, just let it be.
I use Security 2.0 to describe the new trends in network security area, e.g. internal control, identity and access management, and etc. That differentiate themselves from the original anti-virus plus firewall plus IDS. No matter what you call them, they just exist there. right?
