I've been enjoying this new addition to my vocabulary lately. But I find I can only use it if I put a little extra zest into it, as if to say, "I don't usually use words like 'zeitgeist', but this one's so dang zippy I just have to!'" otherwise I feel I'm getting a little too deep into SATish waters for my own taste. Anyway, I have noticed any number of odd things in the zeitgeist lately, like the preponderance of Yetis in modern art. Even the word zeitgeist seems to suddenly be in the zeitgeist.
