Attached Link: DAZ3S/Renderosity/RDNA site comparison

I don't know that I'd atach any great weight to it, but if the relative figures really interest you try Alexs. Using the top level sites (I didn't try just the forums, since they aren' separate sub-domains at all sites to enable comparisons) it looks like DAZ and renderosity are roughly comparable: http://www.alexa.com/siteinfo/daz3d.com+renderosity.com+runtimedna.com
