When I look for answers to my own questions, I don't browse categories. I just type the right stuff into a search box somewhere. I don't think categorization will help people find answers.

Most of the time, people asking FAQs either don't care that the answer is in the docs (Perl already comes with 9 perlfaq docs) or they don't know that the docs exists. Creating a new section of PerlMonks or spending a lot of time categorizing previous answers doesn't solve either of those.

Even though every six hours I post a part of the perlfaq to comp.lang.perl.misc, people still ask those questions there. I don't see technology or library science ever solving it. :)
