Why do you need to add cream or milk to chocolates in a fondue pot?

Ok, so I just got a fondue pot (not fountain), and all the "recipes" I'm seeing seem to include adding cream or some type of milk to the chocolates in the pot. I don't understand why.

The taste is better, (you can also add some kind of liquor, Bailey's, amaretto, brandy, etc), chocolate on its own burns very easily, (and tastes and smells absolutely terrible once it burns), and the cream prevents that, and the texture is improved; it's smoother and silkier, and thinner, which makes it more suited to dipping.
