Unsprung Media is built upon the SquareSpace platform.

 My criteria for choosing SquareSpace:

• I had to be able to easily and simply use my own URL / domain.
• I did not want to host anything, or deal with any infrastructure.
• The interface had to be simple and powerful.
• I had to be able to incorporate multi-media widgets.
• The system had to be scalable, and be able to handle bursty traffic.
• I needed to be able to easily incorporate my own advertisers and sponsors.
• The company had to be stable.
• The user interface had to exceed my expectations (and they were high).
• I had to be able to fully customize things if need be.
• I did not want to pay a fortune.
