Google has never indexed all the mailing lists on haskell.org properly. I never found out why, although I believe John Peterson looked into it at one stage and concluded that it wasn't easy to fix. Google does index the mirrors though (mailarchive.com, gmane.org).

try googling for "albus dumbledore tutorial haskell". i get 32 results, none from haskell.org. something is very wrong there.

checking the simplest things first, here is www.haskell.org/robots.txt:

   User-agent: *
   Disallow: /
User-agent: *
   Disallow: /pipermail/

that puts an end to list archive search by any decent search engine's spiders
right-away, doesn't it? in fact, the first entry makes me wonder how we get
any results at all from haskell.org?

   http://en.wikipedia.org/wiki/Robots.txt

i don't know how the different wiki formats and redirections affect things,
or what the different servers at haskell.org have to say about this. and i know
that html pages at haskell.org use the robots meta tag for fine control, but i don't know how robots.txt and robots meta tag interact. i suspect that with
that particular robots.txt, google will index nothing, unless someone else
points directly at a page, and that page's meta tag allows indexing.

cleaning up that robots.txt should help, but someone must have put it
there for a reason?
