I concur. From personal experience, I've added the following line to my modules:

The public support forum of this module is http://perlmonks.org/.

This has relieved me from the burden of being the only knowledgeable person to answer questions, and also has relieved me of the burden of providing polite answers. If I'm not in the mood for a polite answer, maybe somebody else sees the question and can provide the answer from the FAQ or Troubleshooting, or find out that the question is not at all about a module by me.

I also want to thank the people on this site for answering questions and generally keeping a civil tone.
