Normally I'd stay out of a conversation like this, but I have to say that I agree fully with Adam and, like him, feel that this whole topic is a bit uncalled for and inappropriate. This is a personal choice on Alex's part, and as far as I know he asked for no criticism on his site or his methods. Also, as far as I can tell all of the content on the site in question is 100% original, created by Alex, and as such he has the full right to do with it whatever he pleases. Helm, I think a quote from your original post sums it up pretty well:
Obviously, running a website takes money, and a webmaster is free to ask for compensation on any thing for his site, and whomever is willing to pay for it, that's their choice. Nobody should be able to make them stop. In the end, if there's a demand, people will pay, if there's no demand, Kon will likely remove the service.
Also do you think your stuff is really that great to warrant someone paying money to see it? Just a thought..
I think this statement is a bit off base, too. Couldn't it be asked of anyone who works professionally, who charges a wage for their work? The only difference here is that Alex created his work first, and then attempted to sell it. Not all artwork that is sold is commissioned. Many people just like to buy paintings, or, in this case, pixels. Asking if he "really thinks he's so great" is a bit insulting, too, as it, in my mind, implies that he's arrogant or egotistical. Is every artist attempting to sell their work an egomaniac, then? Apologies if I've misinterpreted your meaning, but this is how it came off to me.
Finally, and maybe most importantly, in regards to the question of a "conflict of interest": has one arisen? Has there been any change or decline in the quality of Alex's moderation or contribution to this site (outside the realm of, say, perhaps having been a bit busy designing his new site, of course)? I don't know, of course, but if there hasn't, then I'd argue that this is a non-issue.
Apologies, again, if I've misinterpreted or misconstrued anyone's words.
