I have a interesting position (from reading many of the posts above), I started out with PHP. I switched to Perl because I wanted to get away from web programming and most of the really cool "features" that I liked in PHP were inspired by Perl (case and point: the preg suite). So if most of the things I love about PHP were inspired by Perl why not go to the source?

Recently, with Perl, I have done things that I could never do with PHP (well, not easily) and that alone brings me excitement. I believe "Making easy things easy and hard things possible" is very exciting to any programmer.
