Very nice work Andy.
One place I've noticed a potential source of good articles is a
Google news search:
http://news.google.com/news?q=perl
In particular, there are about 5 or 6 recent ZDNet White Papers of
Perl success stories by way of O'Reilly Media. These include the
Oxford English Dictionary bit, CMU's heavy Perl reliance, assorted
medical applications, and the story of Sweden's pension system. All
stories many of us have heard about, but I'm not sure for how long
they've been making it into the news indexes.
