Eh -- I've looked at PERL code, and that's about it. Have some friends who code in it, and their favorite thing to brag about is how much they can do in one line... how efficient the code is...
To me, the syntax looks a little confusing (but so did C++ and VB the first time I looked at it) --
My advice would be to pour yourself into one or the other... I would think it'd be really time consuming and confusing to get really good in both at the same time (probably spin your wheels a bit, too, trying to remember which was which).
ADO is good stuff, and dotNet is coming out soon, with a little different treatment of ADO, but it is going to be in there. Anyone who's good in dotNet (and ADO) should be able to do just fine in the job market. That's where I'm putting my eggs at the moment...
It's such a hard question to answer. I'm sorta biased to VB and VBScript, though, because it's so readable and easy to code in... easy to debug... all that jazz.
