I know I've been less-active since being forced to brush up on my Java skills; my current employer has all but banished Perl in favor of Java and .NET -- if I move to a group where Perl is still accepted (most the UNIX group, unsurprisingly), I would have to take a fairly significant (read: mortgage-threatening) pay reduction.

Fortunately, they haven't tried to stop me from using Perl on my desktop, so most of the development tools I use are Perl (svn automatons, code formatters, utilities to search code, etc.). ;-) Unfortunately, none of those tools have prompted good Perl questions, and my Perl skills have stagnated a bit.
