Perl Monks

Originally part of the Slashdot family, it is a very useful place to ask and answer questions.

There are a few bona-fide titans on there and a much larger number of budding experts who will happily compete to respond to questions: as a result, answers to well-formed questions tend to come very quickly, and discussion ranges from quite erudite discussions of algorithm efficiency to very basic FAQs.

Sometimes one sees eerily similar conversations there and on the mailing list, as someone asks the same question in both places.
