As for marketing, some of the best marketing was done by people in this forum and all the multitude of similar forums across the web.  The first thing that was said to newbies, back when the Daz bases were free, was inevitably "Go to Daz, download V3/V4." The first thing.  So we have ourselves to blame for that. ;)

In any case, Renderosity makes money offering whatever sells. If that ended up 100% Genesis, so be it.  But in order to market effectively, a site like Renderosity would have to dedicate itself to doing exactly what Daz did with its new figures: devote as many pages as possible, including a permanent front page presence, to the newcomer. I don't see Renderosity doing this because it's not their business model.

SM might be able to do it, but, oh boy, they'd have to seriously re-tool Content Paradise. It is not a fun place to browse.
