This post is a sacrilege. :-)
CPAN at this time contain ~3000 modules. If you search CPAN for something and you don't know exact module name and just search by category and keywords - your chances to find the best of existing solutions are near ZERO! As merlyn wrote some time ago - at CPAN we can found 37 modules only for CGI/HTML templates!
Comparation of some modules doing ~identical things sometimes exists in special tutorials or reviews, but you must find these reviews first and most of these reviews in fact incomplete and/or obsolette and explain only one (author) opinion.
I think that CPAN structure must be redesigned (I have no idea about how this can be done now) or at least powered with new indexes.
In last 5 hours I realize one idea about such indexes: Modules Popularity Index. As popularity criteria I take how much results will be found by Google for query:
I think what indexing algorithm must be strongly improved to make this index really usable, but now it interesting too.
Any ideas/comments about CPAN improvement?
