I mentioned my one module on CPAN (String::Random) to a friend yesterday, and got the response "You wrote that?" Honestly, I was shocked that he'd heard of it. (There are so many modules on CPAN that I doubt most Perl programmers have heard of 99% of them.)
I decided to Google for the module a bit to see if there were many mentions (fully expecting to find some "I looked at the code, and my eyes are still bleeding" comments), and I was pleasantly surprised to find this rather old tutorial on using the module: http://www.perlmonks.org/?node_id=88021
I also found a Ruby port on GitHub: http://github.com/repeatedly/ruby-string-random
So far, I haven't found anyone ripping into it, but I'm sure it's out there...
