Yes, I've done professional work in Perl, C#, and Java. These silly stereotypes need to end. Think what you will about PHP, it's not as horrid (now) as most people like to assume, it's mostly just misused. Oh wait, it's trendy to hate on PHP now, which is really the problem I'm was originally addressing. People want to jump to another language as soon as they've worked with one long enough to truly become aware of it's handicaps (or even be able to parrot other people's gripes) and then repeat the cycle. Even as much as I (regretfully) look down on ASP/.NET, if that's what you want to be good at, go for it. I'm sure it's plenty capable if used correctly.
All-in-all it's plenty fine when I see people writing off PHP devs, in my case, it's mutual. I don't write off ASP devs just because I think ASP is restrictive to my style of programming. There are "better" tools for the job, but often the claim that something is the wrong tool is rooted in... well.. yeah, I'll stop there.
