On and off for four or five years. It's never been my first, nor was it ever my single primary language until I moved to my current job, as I usually juggled php while doing perl/java full time.
Ease of embedding code in markup similar to asp or jsp without the need for extra libraries (like you do in perl).
My next challenge is modernizing old projects.
I write in a variety of languages. At my last job, I wrote the software that (still) handles the monitoring data for the largest fiber optic network in the world.
