Typographical Ramblings on Palatino, and Impact

I'm experiementing with two "unusual" typefaces, and I must admit, I am liking the result. Actually, these typefaces are not unusual at all -- they are Impact for headers, and Palatino for body text. Palatino, in particular, is admired by the world of typographers for its elegance, and beauty. Yet, the dogma among web designers is to not stray from Georgia, Helvetica, Arial, Times, and Verdana -- however, I've checked browser support charts, and these two type faces seem to have widespread, if not virtually universal support.

Palatino, IMHO, is the most elegant font.Its strange -- I wonder why no one bothers to use these fonts? Sure, they might not be installed on every computer, but CSS allows you to specify fonts to fall back on. Anyways, I'm just happy as clam about this. Then again, I wonder: are clams really happy?
