Part of it is due to how people here use Poser. There is no point in upgrading if you don't actually use anything that has been added to Poser since the release of Poser 4. And I think that is why many are attracted to DS, it has a Poser 4 feature set with a PBR bolted on.

Poser may be dying in the 'Rosity forums, but let's not kid ourselves - most people (and vendors) here are still stuck in October 2007. I think that is the reason 'Rosity has gone from 4500 - 6000 members online at any one time to not cracking 3000 since the last site "redesign". If you want to see a good example of that - dig through the forum archives - the level of vitriol is the same as today, but back then there was a lot more information available.

Timberwolf earlier mentioned how SM was surveying the forum members over at RDNA. Well, those forums ARE the official SM Poser forums. In addition, that community is more open to letting go of a Poser 4 workflow, IMO - I have no idea where you are getting that "backwards compatibility is most important" nonsense from. Figures that take advantage of modern versions of Poser are sold there - not here. In addition to that, those new figures aren't savaged in the forums like they are here. Nor do they allow vendors to disrupt threads the way the mods do here.

Tools to extend Poser capabilities are sold over there, not here. Subforums to leverage features in Poser are there, not here. If you are using Dawn as your primary female mesh - why spend a single minute here? Your time would be better spent at Hivewire. SM figures, 3rd party figures, or Poser itself - The RDNA forums are where the action is.

There is very little "new knowledge" to gather in the forums here. And if "new knowledge" did show up here, what are the odds that we would get an e-bot notification of it?
