[davi]

It has nothing to do with a preference for complex vocabulary.

When I talk to someone I know has a large vocabulary, I am free to use the best word that occurs to me, and if they think I'm up to snuff, they are free to do the same thing. This makes for a more pleasurable conversation. (Assuming we're actually trying to say something to each other. But if the motivation is to show off, or engage in ego jockeying, that's boring.)

I guess it's more accurate to say that baud rate surges transiently when a rare, but exceptionally precise word enters this sort of conversation.
