Not get all Bah-humbug right before the holidays, but I just don't like to say Web 2.0. I couldn't agree more with this post from Russell Shaw. Ask 10 people what Web 2.0 is, and you'll get 10 different answers.
I will, however, soften my stance a bit. As my good friend Ed Batista pointed out to me at lunch the other day, it's useful as a handle. There are a lot of big concepts about the Internet and how society is using it right now. Web 2.0 is a comfortable place for people to begin to express their ideas about what this means for themselves and their work. It's a kind of metaphor, and metaphors can be useful.
I do think, however, that if any of this Web 2.0 hoopla is going to mean anything for the sector in the long run, we're going to havee to strip away these meaningless metaphors and start saying exactly what we mean. I know that "User Driven Experience" isn't as catchy , but at least it means something.
