I myself very much enjoy reading the reviews that people have done on assorted modules and books. They serve often as a quick tutorial introduction, and there's generally a couple modules in there I might have never thought of using.
Alas, I think there could be a couple more categories for reviews.
Firstly, software. A lot of people use different editors for Perl and other programs that augment their use of Perl. Although these softwares might not be directly Perl related, their reviews can still be useful and pertinent from a monk point of view.
Secondly, I think an webarticle/magazine article category would be in order. A recent
node by
Ovid speaking on an article by Paul Graham is now one of my favorite nodes, and the replies that resulted were also excellent. (Perhaps this review category could be better generalized as offsite content).
Anyhoo, let me know what you guys think, and any other good category ideas.
