My tech niche happens to be in publishing, where, while things may
change a lot, the basics move like molasses. I'm not too worried about
it--I learned the programs on the job, I could do it again, and the
base experience with desktop publishing programs is worth far more than
happening to be hot on one particular incarnation of one particular
program.

Then again, the chances that I'll want to go back into publishing are
slim right now.
