It depends on your geography. What few web jobs there are want Studio.Net, VB, and IIS. Only. The jobs advertised that even mention Java want 10 years experience. (HAH!) I do not have the luxury of moving. At my last position, most of my web stuff was in PHP, with Oracle and MySQL. I used perl mainly to schlep stuff around the Datacenter.
That position was eliminated, and the systems I built were moved to Colorado, and will be ported to VB/Studio, to better integrate into the Ordained Corporate Platform, XP.
I'm thinking it might be time to learn VB and go get that MCSE after all. My kids gotta eat, and at least for now, perl and Open Source platforms won't feed them.
