FWIW, you said earlier "read", while I said "downloaded".  There's a 
difference, for those of us who download to cache (increasing the cache 
size to some gigs to allow it), and then read later, when everything's 
local so it can be done in real-time.  (Actually, I only normally do that 
on binaries since text downloads fast enough it's not worth the hassle, 
and I've not done binaries in probably a couple years or more, now, but 
the point remains, there /is/ a distinction, and in text groups with nym-
shifters, etc, it could still be worth caching to score first, if that 
was the only way to properly score before actually reading, too.  So it's 
a distinction that does matter.)
