These percentages are valid for the sites running arbitron; however, sites
receiving a restricted set of newsgroups are not running arbitron in general.
I know of quite a few sites around here that only get comp, news, and sci;
while my evidence is only anecdotal, I am almost certain that there is a
bigger gap between the propagation of (comp,sci,news) and (soc,rec).
