I still like extravert, personally, because all the other english words which borrow that latin root are spelled with an "a"...extra...extraordinary, extraterrestrial, extravagant, extraneous.

For some reason, when I hear "extrovert" I picture someone who enjoys socializing, whereas when I hear "extravert" I picture someone who "turns outwards" and seeks external stimulation - as the latin roots dictate. This is probably because I first read "extrovert" in popular usage, and first read "extravert" in reference to Jungian typology, and the two definitions are slightly different.

I suppose making English consistent is a lost cause though, and I ought to just give up.
