Just as art being subjective, I prefer to think this type of thought being descriminating. Even if you think this way, it doesn't have to be pinpoint in public in such a manner. Renderosity's acceptance of merchant stuffs made me think of diversity. If there are no 'loads of junk' as you mention, will you appreciate the 'good quality items' more? I have seen quite a few artists, when they first started selling, their items were average, but then as they create more stuffs, it gets better. If they were not given a chance to sell their first product, will they turn up 'good quality items' someday? I've also seen some merchants with 'see if it will sell' or 'I just need to sell 1' attitude, but well if people do purchase their products, it's their business. Maybe it's not as bad as you think. I don't really mind glancing through the marketplace, afterall you can just click for details on what's attractive to you.
