I was around for web 2.0, and it felt like a substantial change over how the web worked previously. It was the first glimpse that the web was capable of replacing the desktop apps we were accustomed to, while simultaneously adding new capabilities that didn't exist in desktop apps. There was a lot more to it, but to the casual user that was the most obvious difference.
This was the first thing I've read about web 3, so I didn't need to grep my brain to find and remove any existing notions about it. As someone coming in late to the party, I agree that installing a browser extension seems like a deal breaker. Web 2.0 was about getting rid of browser extensions. It also sounds like web3 is missing a killer app. For web 2.0, Gmail and Google Maps and YouTube were all immediately useful to all web users. Web 3 doesn't sound all that compelling to a lay person.
