Larry Wall is a great guy. Perl brings me back to the days of my Pentium 2, tinkering about with my primitive IRC bots.
Back around 2000, I was working at a mid-size company that stored tons of data in a company intranet. There was lots of useful stuff locked up in there, but hardly anybody ever used it because the web interface was clunky and slow.
One day I had a brainstorm, and after a few evenings' Perl hacking it was up and running -- a conversational interface to the intranet, running over AOL Instant Messenger. You added the bot as a buddy, and then you could query the intranet a bunch of different ways; IM it a client's name, for instance, and it would ping you back with their contact information, who their account reps were, what projects they were associated with, etc. (Which is very useful when your phone rings and it's someone you don't recognize.) Pretty nifty stuff, for the time. Everyone had AIM running all the time anyway, so this turned out to be a big hit -- much bigger than I ever expected.
And I probably never would have been able to get it working were it not for the ease of programming in Perl and the ability to tap into CPAN's massive library of code and take advantage of modules like Net::AIM (http://search.cpan.org/~aryeh/Net-AIM-1.22/AIM.pm). So thanks Larry, and thanks to all the Perl folks who contributed to CPAN over the years!
