One of the problems with terseness is that it can make code completely unreadable. You can write perfectly readable code with it, but the fact that it's easy to make dense, inscrutable code can make things a nightmare when you're looking at what someone else has made. Especially if that person is a Real Programmer[1].

Of course, a lot of people very much resent the idea of a programming language forcing them to do what they see as pandering to the lowest common denominator (That's what comments are for!). It really is up to the community as to how much description they really need.
