Do you like|hate books with words or places you need to look up?

When reading a book that has a word you've not heard of before, does it annoy you that you have to look it up? Or do you like learning a new word?

--Does a little go a long way? Lookin' up a word or two is okay, but too many and it's a turn off?

What about a place you haven't heard of before?

I'm curious.

I recently had a conversation about this and we had different opinions. So, I'd love to hear yours.

>>>The title should read "books" and "places" :)
