For me, the term was very useful, because it marked the time when new tools (eg wordpress) made it possible for me to publish to the web, without knowing anything about html. So:
Justin calls for death of 2.0 as well, and I started writing a comment to object, but realized: it makes me a dinosaur. The usefulness of 2.0 to me is to refer to a web that is already gone. web 2.0 replaced 1.0 … and is now… just the web. and there’s no point in saying 2.0 anymore, unless you are interested in talking about how the web used to be, way back when. Waaaay back in early 2004.
So I am on board. Web2.0 is officially stricken from my vocabularity. The web is dead. Long live the web.
