I work at a small company that still uses perl for everything. It works, the company makes money. They'll never move off it. I bet there's a lot of little places like that, but I doubt many are starting new projects with it. Not many of the major modules have a lot of updates recently, but they've also been pretty complete for a long time. If you already know shell/awk/grep/etc it's pretty easy to pick up. Probably will see less and less of it as the people that do write in it continue to age.
