Why not sue EVERYONE?
I'm surprised this oxygen thief isn't suing Microsoft and Apple for writing the operating systems that enabled Twitter; CERN for inventing the WWW; DARPA for inventing the Internet; Switzerland for inventing Helvetica; and the Gutenburg Project for being named after the guy who invented movable type, (thus enabling all of the above).
He could have just hardened the fuck up accepted the poor girl's apology; but NO, that's not THE AUSTRALIAN WAY!
Careful, El Reg; you can be sued for just covering the story most likely...
