JJ just mentioned to me that the 18,000 figure on Perl.org was now out of date...
http://search.cpan.org/ - check out the bottom left corner...
- 20127 Distributions
- 56650 Uploads
- 81688 Modules
- 8176 Uploaders
Perl.org is now updated - wonder which distribution was 20,000.
CPAN is an amazing growing resource - Perl really does help get the job done.
