the dumb question...

My interaction with the Web 2.0/Library 2.0 discussion has so far only been via "print" (traditional and online) formats. I've not been in an environment to hear the term spoken aloud .... beyond my workplace where we hesitantly call it "that, ummm, library ... 2 ... errr... thingo". I note that the podcast in "thing #1" refers to "Learning point oh" and "web two oh".

So if I was to engage in a person-person conversation about "Library 2.0" ... should I confidently refer to it as "library two", "library two point oh", or "library two oh"?? Is there a consensus? Thanks !
