I don't think this is a fair comparison. From what I've understood by reading both posts is that each writer comes from a different background(I can't think of a better word right now) and that's what's causing this difference of opinion.

The first writer is making a living from photography as stated at the bottom of his post: "John B. Mueller is a photographer based in Ventura County, California."

The second writer seems to be doing this as a hobby. At least I'm assuming so since he's been taking photos for 27 years and claims that he has not made any money from it. So I really don't think that this is a fair comparison.
