Yup, perhaps you are right!
But, I think a layman may not be so much aware of dA...the buyer may himself be a designer but he may still buy a template if he needs it in case he is a way to busy, sometimes may be due to lack of ideas or lack of time...could be any reason! But, also finding a right designer & best template may still be difficult, browsing through tons of deviations ain't easy & especially more so if you are at lack of time.
Well, its just my thought...communication helps to wipe of the mind cobwebs if I may have any!
Yeah it's true. I was just wondering at the possibility at it If there ever was such a thing it would have to be its own unique system of doing things -- not just randomly browsing. It would be a system that had to be built.
you're asking designers if they'd buy a design...
well i think it's a good idea, i also thought of this before... but deviantart is a community for artists and i don't think that businessmen look for designs here.
i wouldnt but, for the people who doesnt make their own, as someone already said here, its a good idea, but i really think that, people who needs site for their company dont came to DA to buy it, so a nice online portfolio is better.
