All We Got Was Web 1.0, When Tim Berners-Lee Actually Gave Us Web 2.0 is a reference to an interview of Tim Berners-Lee, "Yes, the original vision of Berners-Lee is now apparently happening, so he's right in a sense there while glossing over the reality of the early Web. But though his vision was largely possible since the advent of the first forms-capable browser, at first we only got what we could call "Web 1.0"; simple Web sites that were largely read-only or at least would only take your credit card. The essential draw of mountains of valuable user generated content just wasn't there. And the millions of people with the skills and attitudes weren't there either. Even the techniques for making good emergent, self-organizing communities and two-way software were in their very infancy or were misunderstood. An example: How long did it take the lowly editable Web page (aka wikis) to be popular and widespread? Nearly a decade. The fact is, most of us know that innovation is all too likely to race ahead of where society is. I run into folks from Web 1.0 startups fairly often that bitterly complain about how they were building Web 2.0 software in 2000, but nobody came."
Tim also mentions those boring things like the Semantic Web, SPARQL and Enquire (the first browser which was an editor and browser).
