Kyle MacDonald finally accomplished what he set out to do a year ago; trading his way up from a red paperclip (posting on Craigs List) to a house. He has chronicled his story on his blog and given many interviews on this subject.
"I started with one red paperclip on July 12 2005 and 14 trades later, on July 12, 2006 I will trade with the Town of Kipling Saskatchewan for a house..."
Was this a result of social networking on the Internet? Yes. Could this have been done without the use of the Internet? Yes, I'm sure some smart trader in the past has done something similar without using the Internet.
In any case it's a good illustration of what is possible if one sets their mind on something and pursues it without any hesitation or fear.
