I would guess he's promoting it because he's proud of the job he did putting it together. It's a
photo site displaying personal hunting photographs. It's not a retail venture and as I recall there isn't even page where viewers can post comments so I don't see how it could be considered to be in any way in competition to this site. I think he's doing a fine job with his site and I quite enjoyed the photographs. His "shameful promotion" is actually just an invitation to look at his photographs. Personally what I find shameful is the way that some are so quick off the mark to be negative and critical. Give the kid a break.
