Subject: CRYONICS USENET Readership Report
Over two years ago I posted message #1179, giving the current
estimated readership for the USENET sci.cryonics news group and
a few other groups, too. I have appended below a recent update,
extracted from Brian Reid's quarter-megabyte-long July 1994 USENET
Readership Report. (FYI: I extracted it via WWW from directory
ftp://rtfm.mit.edu/pub/usenet-by-group/news.lists/)
As before, I have included the listings for the top ten news groups,
a few related news groups, and also the least popular USENET news group.
When reading the statistics below, please don't forget that Tim Freeman's
nine-part cryonics FAQ gets posted once a month to news.answers, the
second most popular news group.
Oh yes, the cryonics mailing list has about 225 people on it,
about one hundredth the estimated readership of sci.cryonics.
Please keep that in mind when forwarding CryoNet messages
automatically to sci.cryonics.

PS: I don't understand why the estimated total world readership
(second from left column) is not consistent with the percent
of news readers (rightmost numeric column). For example,
comp.unix.questions claims 280000 readers worldwide and 5.0%
readership whereas alt.sex.stories claims about the same number
of readers worldwide (270000) and yet 8.0% of the readership.
I think that some of the other anomalies (such as the number of
megabytes per month in news.answers) are due to cross-posting.
