History of computer Symbols (*.*)

 If anyone was wondering what Asterisk Dot Crusade meant - its a search command in DOS for all files with the extension "Crusade".

Asterisk stands for "everything" so for example if I wanted the computer to list everything on the hard drive I would type *.*

Outside computers asterisk is used to denote something special or something angry/vulgar.

 This link from Wired.com tells the interesting history of a few other symbols..I felt they missed a few.
