About 6 or 7 months ago I noticed I was being indexed by a search engine named Duck Duck Go. I went to the main page and it seemed interesting, but I never went back. Today I read that Duck Duck Go is written in Perl. I still don't know that I'll start using Duck Duck Go, but I find it very interesting that what is likely a very large project is using Perl. People who talk about the lack of scalability of Perl or the poor performance of Perl should take notice.
