I recently stumbled across their site and thought it might be interesting to see what they knew about the users of dor.org.
It turns out that Quantcast claims to know quite a bit. Their summary says,
This site reaches approximately 18,35 [they mean 18,350; see the graph] U.S. monthly people. The site attracts a rather female, primarily older, more educated group.
Dor.org's recent traffic seems to show a sharp increase since mid-July.
However, the demographics underlying that traffic don't bode well for the future.
It's difficult to see how an older, mostly female demographic with no kids left at home can do very much to help DOR recover from its ongoing malaise, no matter how well educated it might be.
