I use scripting languages almost exclusively ( I haven't written C in about 10 yrs). In order of preference, JavaScript, Python & PHP.

Science shop - most of our development is in perl (OO style), C and Fortran, with a smattering of whatever else we are saddled with.

Ruby, Hecl, Tcl, C, occasionally Javascript and other things like Erlang.

C#, Perl, a bit of scheme and lisp.

C#, Python, Javascript

I use Ruby (via Rails and HacketyHack) the most, but I also code in Haskell, C, Javascript, D... and some others, just not very often.
