The @-symbol

via shady characters
“Like the ampersand, the ‘@’ symbol is not strictly a mark of punctuation; rather, it is a logogram or grammalogue, a shorthand for the word ‘at’. Even so, it is as much a staple of modern communication as the semicolon or exclamation mark, punctuating email addresses and announcing Twitter usernames.
