googling site statistics show that 'rosity is still at the top of the poser-related sites in terms of traffic and sales by a significant margin. Anyone interested can run the same scans and find those results from multiple analytical sources, comparing the top poser sites and see for themselves.

So while forum activity may be low, traffic is still quite high.

I'd say the primary reason activity is down in general is due to a lot of people moving on to other interests, more advanced software, etc. There's a lot more available to the CG hobbyists now than there used to be. I do agree that the forum software needs work.
