alt Hacker NewsWeb 2.0 has a few different definitions but one of them is when HTML pages started to contain significant JavaScript, and another is when websites started to be middlemen between users rather than users interacting only with the website operators.

Yeah I think of it as when user to user generated content became prevalent. I think the increasing prevalence of javascript interactivity was more of a response to making such websites more functional.
To give it some value as a term, what Tim O’Reilly meant by it was a shift to participatory, user content driven websites. Blogs, Flickr and Wikipedia were quintessentially Web 2.0 phenomena.
