Although the vast majority of my development work is VB.NET/ASP.NET, I do manage to get a fair amount of perl coding in.

I use perl ALOT on our UNIX servers to eliminate the need to telnet sessions (I've pretty much replaced that with socket servers through a web interface), as well as to handle routine maintenance and clean-up and any other task that I don't want to deal with.

Perl serves to make my job as a developer easier. I'm actually going to use it in an ASP.NET web-app, in the near future, to generate a massive amount of SVG from a SQL Server database. Because of the modules available, I'm going to be able to write this in much fewer lines of code and in much less time.
