Popfly, Microsoft's Innovative Mashup Programmer, Cancelled

From John Montgomery comes word that Microsoft's Popfly project has been cancelled. I was bullish on Popfly, predicting that it would become the power-user's entrance to Silverlight.

I have had a history of wishful thinking about "restoring the bridge between power users and programmers." I think Microsoft's Powershell is incredible and it absolutely boggles me that it's not gotten more traction.

Is it possible that I'm just clinging to an outmoded value? That these potential bridges don't get traveled because people aren't interested in the destination?
