I think LF wants to put it up somewhere; kernel.org is certainly a
possibility too.  OTOH if it's in the kernel source, others could update it
too.  I've always really liked the way stuff in Documentation/ stays
current...

I was going with 1.0/year as a working number.  The period v2.6.22..v2.6.26
(July 8, 2007 to July 13, 2008) had 2294 distinct contributors.  About 1000
of those were a single patch.  If we say that >= 2.0 is active, then the
number goes to 1200.  I could just say "over 1000" and be happy with that,
I guess.

Good point, I'll add that.  Everything else you pointed out is good too,
consider it all added.  After LWN comes out, anyway.  Thanks for taking the
time to read through it all.
