Quote - I think the answer is "yes". Years ago when checking out the renderosity gallery, I've seen more Poser posts than today. The amount of Poser posts have decreased a lot. You have a lot more photographs , DAZ and VUE pics these days.

I wonder if that might be due to changes in the way people use the galleries, though.

PoserWorld supports Poser and DS, and their e-mail said they felt BOTH the Poser and DS user bases were shrinking, so I don't think DS is really the issue.  Though perhaps DS users are more likely to post their images at DAZ.

Taking a wider view...it seems like casual users (as I suspect many Poser and DS users are) have moved to social media.  Rather than posting in the galleries and in forums, they post on Twitter, Tumblr, etc. 

Renderosity also changed their rules at one point, and started limiting the number of images you could post to their galleries, and that might be an issue, too.
