I'm going to swipe the padre's curmudgeon hat here, and say that many of the initial offerings are indeed "fancy pants words" that obscure and impeded communication except in a small group. For clarity of meaning, "tree-shaped" blows "dendroid" out of the water, for example. Some $10 words are beautiful and irreplaceable (like noctilucent), but the amount of time I spend around people who don't have English as their first language predisposes me to preferring 50 cent words, tyvm.
