Hearing that from you also means much (and now the feedback loop of
self-congratulations speeds towards singularity)!

Blogging also seems to have reached a plateau, although it is somewhat
index dependent and might be local to the anglophone world. However, both
GIMPS and blogging represent activities where we cannot measure efficiency
that well. However, the linear increase would measure the amount of extra
FLOPS machines now achieve beyond system maintenance and ordinary work
Car fuel efficiency might be of interest, as is the amount of losses in
power systems per Watt put into them. We might want to find out how much
and how many different chemicals one kilogram of coal can be turned into.
For news we might want to find indices of how quickly a particular piece
of news reaches 50% of its asymptotic recipients. For software we might
want to measure amount of time lost due to swapping to hard drives,
processes negotiating out of deadlocks and number of lost or colliding
packages in different networks. Of course, the important thing is to
measure this as "per capita" rather than the aggregate amount - as we get
more computers we certainly have more packet collisions, but the
interesting thing is to look at the efficiency of the system on average.

Not all math geeks run GIMPS (cries of surprise and outrage), so being
rarer than one in a million is not that surprising. I wonder how many math
geeks there are worldwide? Maybe GIMPS is missing emerging crowds of geeks
in China, just itching to search for Mersennes?
