Amazon lists 106 different Perl books. Many, of course, are practically worthless and some are out of print. However I suspect that there are some real nuggets out there beyond the obvious O'Reilly's Llama, Camel, Twin Owls and Manning's/Conways OO book.
So, how about a Bibliophile's section, to elicit reviews of the hidden treasure out there. Sure, some reviews are available on Amazon, but most are too brief to be really useful. Motivation for superior reviews could come from bonus XP for detailed and knowledgeable reviews. A link to Amazon to the item in question, might over time, generate some revenue to provide those Perlmonks T-Shirts and Coffee mugs we all crave :-)
