Reading all these posts I detect a strong undercurrent of hostility towards folks that like to take classes. "Card Collectors". I think it is important to recognize different folks learn in different ways. It is not how many classes or how rapidly a person takes the certification classes, it is how he/she acts once the class is completed.
Getting AOW may be a useful thing for a newbie diver to gain confidence, but if the person truly believes that they are "advanced" they have more problems going on than just in the scuba realm...
On the other hand, if a relatively new diver goes through the AOW course and gains some confidence and additional skills to work on, then the person may go on to continue diving and with increased enjoyment--rather than getting OW certified, not wanting to continue diving, and quit the sport....I think the statistics show a lot of folks get OW certified and don't continue. If going on to take the AOW class gets them out and diving more, I say "great".
