An excellent, succinct, sensible description of web 2.0. Of course it'll never catch on because it lacks the hype factor. His punch line: "Web 2.0 apps are different from 1.0 apps in that they're native to the web, and you can do things with them that simply were not possible before."

My metaphor for Doval's concept would be web 2.0 is a STEW... which came into being because a bunch of (not necessarily related) tasty ingredients became available at approximately the same time.

One small quibble: This doesn't really mean that a higher quantum-level web3.0 tech-stew will not bless us at some future date. [Not holding my breath.]
