Oh come on. Pull yourself up by your own bootstraps if you don't like that. Find a hot new language and play with it in your spare time. Start an open source project with it. Contribute to the community. Then apply to jobs with that knowledge and skill set on your resume, and you'll break out of that role. Just have to want it.

Agreed, I worked in .Net and Java for a few years, decided I wanted to get back to PHP, started up an open source project, started talking about it and mastering the language in my free time. Now I work a PHP job that I love and I like to think having a couple thousand lines of example code out in the wild gave me an edge.
