This may seem like a snitty little tirade, but it's something that bothers me a lot. People use the term "web 2.0" to describe new, web based businesses, and I think it's just so much jargon.
I've suggested that Twitter is just the Internet equivalent of Sherlock Holmes' London Times, that Facebook is the bulletin board in the campus commons, that RSS is a throwback to flat files of the 80's.
Web 2.0 is an Edsel with fins.
This pretty much falls under my "there's nothing really new" cynical tirade. The more optimistic side of me knows that there really are new and innovative ideas, but let's face it, those ideas involve things like Velcro, magnetic levitation trains, or the backbone of the Internet itself.
But "Web 2.0" doesn't hit the world of dreams and wonder, unless you count "I wonder about that dream..." Just because you say you're doing something earth shatteringly innovative doesn't make it so.
It gets back to my argument about tool users versus the folks who create the tools. The things we do on the Internet are amazing, but they are amazing because of the amazing invention of the Internet itself, or "Web negative 1."
But bells and whistles do not make a fundamental shift in the universe.
