the article says:

Fourth, library quality and usefulness (more subjective here). There’s a lot of overlap and, well, cruft on CPAN. There are over 300 Acme (joke) modules.

well, that reminds me of a famous quote of merlyn:

Because Perl's so durn easy to use we got time to play around impressi

each other. :)

(at comp.lang.perl.misc)

so even the number of libraries/modules doesn't tell you how great a repository is. in perl, many things aren't needed which are in other languages (and probably the other way round).

just adding this as another thought.
