I spent part of this past evenig re-reading The Hobbit, and a thought occurred to me. In the LOTR movies, there are Orcs and Trolls and Uruk-hai and Wargs. There were Nasgul and many other varieties of nasty evil thing, and yet...not a single goblin. I don't remember enough about the books to say for certain that there were goblins in The Lord of the Rings, but there were goblins aplenty in The Hobbit. Given the extreme variety of creatures, and even the variations of look within the Orcs, I'm surprised that there was nary a goblin or even a whisper of a goblin in the movies.

It isn't a big deal, but it is still puzzling.

UPDATE: OK, so the orc/goblin thing has been explained to me, and I've re-watched the movies and re-read the books. I take it back, though I still like the word "goblin" better than "orc".
