I liked this post for the parody it makes of the current use of Web2.0 and other terminology, especially as this is relevant to what I am doing for work right now.
I do still think that you can adopt a web2.0 style to what you do without having to pass any kind of test for compliance. Of course this is part of the problem as anyone can call themselves, their service or product Web2.0 but to be honest getting hung up on that crap is silly, as would any attempt to make it a test like ISO standards
