Jack the Twitter
Beware if you use the micro-blogging service Twitter as you might just be hunted down by Jack the Twitter.
Jack the Twitter is a fictional character written by Marcus Brown. Using messages left by individuals on Twitter Marcus Brown is creating a fictional narrative in which Jack the Twitter appears to be stalking Twitter users through the dark streets of London.
Marcus is weaving a narrative around messages found on Twitter to make it appear that Jack the Twitter is secretly spying on them. Each individual narrative is shown on a Google Map, so that over time the created map will become a large site specific narrative canvas.
This is such an inspired idea, although I might just now stop geo-tagging my Tweets.
