Web 2.0 isn't that bad. Its an awful name but it makes talking about the current state of web apps so much easier, rather than constantly saying tagging/social/web/rounded corners/ror you can just go web 2.0.

I do agree that web 3.0 is an awful name. My current pet peeve is the missuse of 'community'.

"Community: We have more than 1 user!"

Web 2.0 is bad enough! though I don't have any qualms with passionate. As you have to be passionate about your business in the first place. Although being passionate about something in itself is not a guarantee of being successful either.
