I agree. Every RecentChanges page contains links to 13 other
RecentChanges, and one of them changes its URL each time the page is
loaded. The other special: pages like statistics, all pages, most
wanted etc. seem to be good candidates for robot exclusion as well:
they stress the database but don't provide much useful information for
indices.

Regarding talk:, wikipedia: and user: pages, I don't see any reason not
to have them indexed.

Diff pages seem to be useless to spiders since the same information
is contained in the two article versions.

Remaining question is: what about article histories and old versions
of articles? Do we want Google to have a copy of every version of
every article, or only the current one?
