@Moriador    "I guess it depends on why you want to sell content. I think (though I certainly don't know) that a lot of vendors decide to make their products available for sale, not because they expect to make a living wage from them, but because they want to release them for people to use (which is its own kind of joy) for the love of simply making them and seeing them rendered -- but at the same time, they'd like to recoup at least some of the costs."

      I certainly admire those who make art (of whatever sort) for it's own sake but admit to being a bit greedy and a lot selfish.  I like the air of exclusivity and will probably only share my clothes with a small group of like minded weirdos (don't ask). 

      It would be interesting to see sales, membership, and visit figures for the bigger sites.
