Teaching people how to see can be done through multiple techniques, I am sure (could be wrong) the same professor would also advocate to bulk load 10 frames and choose them well. I think your premise is so mutually exclusive thinking; your premise with easy access to shooting and reviewing, photographers should be better, and since we have no more brilliant photographers today than before, taking too many photos is in fact a detriment. Sorry Clive I dont agree, here is why, I bet when latex paints came on the market, it probably provided greater access to fine art painting, but were there more great painters after latex proportional to the growth of population and those studying fine art? I bet not. Sure it was prob easier to paint without cleaning the brushes in turpentine and all the slow aspects of oil painting that prior artists had to endure. See what I mean? Your A+B should equal C approach is too presumptive. There might have been more fine art painters using latex but that doest mean that there was a statistically significant number of great fine art painters than before as compared to other arts (music, dance, photography, etc). I think what we see is with access comes a lot of mediocrity, but that doesn't mean there are less great ones.
Personally I do bulk load 10 or so frames but I wouldn't judge my friend if he/she fired off 36 frames in 10 seconds. In my book, the more photography folks do the better, they are seeing, reguardless method of capture and intent. I say use it as an opportunity to motivate yourself, not to be saddened that there is such bad form out there...
