I think there may be a difference in Philosophies involved. DAZ gives away the software and supports it with content sales which is why they put so much importance on content: that's what pays for the whole thing. Smith Micro's view is that they sell you the software and YOU are responsible for creating the content. They aren't in the content business, they are in the software business. For better or worse. DAZ is much better at fostering a community that creates content because that is their business. It's a marketing issue, not a technology one.

As far as pretty girl vs other content, I spend plenty of money on other content. If you aren't seeing it, you aren't trying very hard. Either here or at DAZ
