Uses? Runes had loads and loads of uses, even more than the really important ones listed so far - for communication and protection and charms and divination. Important uses too. Mo traced out a few patterns on his desk top as he considered other uses over time.

Oh, obviously. Mo raised his hand. "Decoration, too, sir, which I think goes along with what West was saying about being used symbolically. People will wear runes or paint them or carve them onto prominent and visible places. I'm not sure if the people who put them on pottery or jewelry don't really believe or don't understand what they really mean, although I think there are some people who like the aesthetic AND want the magical value derived from using the rune."
