The Linux desktop is not a programming language. I would expect Linux developers
to be aware of the various Linux programming community areas.
I would not expect Aunt Sally in Accounting using Linux on her desktop to be aware of such things, any more than I would expect a match.com user
to have a Perlmonks handle.
However, I would expect the programmers of match.com to have a Perlmonks handle, and know about rt.perl.org, and so on. That's what I'm arguing here. To be an effective Perl programmer, you're in the community because that's part of being an effective Perl programmer. Hence, the "PERL" shibboleth is valid, as far as I'm concerned.
