Wow, what a marathon thread. As a newly-minted OW diver, I'm going to say that I've never harbored any delusions of diving without seasoned buddies and a guide/DM who understand that I'm a novice and shouldn't be left floundering about or taking unncessary chances.
I do think of the 2-day course as more of a discovery or pre-cert qualification, but that's just common sense talking; and if you throw out common sense, it really doesn't matter how many dives you're taken on before getting your card: I was sitting in my LDS waiting to head out for an OW cert dive when two 20-something frat boys walked in and said "We want to go diving today." When they were asked to put their names down for tomorrow because the boats were full for the day, they said "We can't do it tomorrow, we're flying out tonight." After the girl running the shop told them that they could die if they do that, one said, "Nah, we've done it before." The other said "you can't live forever, you know" as they swaggered out, presumably to look for a dive shop with open spots for the day. I don't even know if these guys were certified, but I certainly don't see how putting them in a 3-week class would change things.
Finally, I wonder how much the classroom/reading/video time should matter in the equation. I spent about 10 hours reading the text cover to cover prior to the class, and knew it well enough to not miss any questions on the exams, but nearly everything in the book was later detailed by the instructor at some point in the course. For motivated self-studiers, it sounds like classtime is something that can be pared down or compacted without dramatically impacting a new diver's safety (or am I mising something important)?
