In terms of topics, I have no problems with questions about how to use Perl (e.g. "How do I get Perl to run under IIS?" or even "How do I compile Vim with Perl extensions?"), but I do have problems with questions about tools that get used alongside Perl (like "How do I install Apache?" or "What's /etc/passwd's format?"). Some questions are borderline ("How do I get Emacs to properly indent and hilight my Perl code?"); what, you expected an easy answer? :-)

I think that I'm a little more tolerant than you are when it comes to no-effort questions: I'm willing to believe that the questioner doesn't know where to look, or even that they're not aware that they're expected to look before asking. (This second view is annoyingly prevalent, it seems, among VB weenies, going by the VB weenies I've worked with.) On the other hand, I'm also quite willing to consider RTFM a useful, even helpful, answer to a lazy question. I've even made something of a habit of upvoting terse replies to questions that show little effort.

So I guess my boundary is pretty similar to yours.
