Brian,
You're welcome to copy the robots.txt articles and/or data. They're
under a Creative Commons license specified at the bottom of each
article. Obviously you can also link to them as well. Is there
anything else you'd need?

With regards to the robots.txt and validation data, it is pretty easy
for me to gather statistics. I already have all of the data
(validation messages, doctypes, source of charset info, etc.) stored
in a database. Lately I've done a little Google advertising and it has
been interesting to see the crowd it draws -- the incidence of pages
with no doctype has gone up. This suggests to me that the keywords I'm
 using are finding newcomers to validation.

I still don't know how to reach my target market which isn't really
novices (although they're welcome) but Webmasters of large sites who
want their pages to be valid but can't possibly hand-check them all.
Once I start attracting them, my statistics will change.

Cheers
