on my personal account I haven't seen a decline and I'd rather guess that we 
are raising the numbers over the years. However it is hard to get verifiable 
numbers. At least email usage has been constantly strong.

Sounds about right.
The standard OpenPGP 4880 and the upcoming RFC 4880bis maybe worth a look
if you are interested in more details.

A long standing challenge of OpenPGP was how to find the public key of other 
people, a modern solution that is becoming more widespead is
