[Multiply hosts by 100 to get approximate numbers of
computers in the world at the time.  For instance we
should be approaching about 400 million computers in
the world at the time of this first edition.]

[Multiply Hosts by 10 to get an approximation of the
total number of people.  Early on, this was probably
a smaller multiplier, as there were only 7 people on
the UIUC login list at the time:  half of these were
not logging in on a regular basis.  Thus my estimate
that I was about the 100th person on the Internet as
I presume our site was not the first nor the last of
the 18 new sites in 1971, so approximating 9th, plus
the 5 already there, we were probably around 14th or
so, though they tell me we were actually earlier, to
facilitate transcontinental traffic.

Sticking with the conservative estimate of 14th, and
with the same numbers of people on each of the other
nodes, that would have made me the 99th user.]
