What company/product were you most sad/surprised when it shut down?

This list of past websites shutting down recently reappeared in my news feed, everything on the list brings back some decent memories of apps past.

Some notables to this list were:

1. Parse
   Which of course looking back now, it’s probably for the best.
   
2. Rdio
   
   
3. Drop.io
   Another Facebook acquisition gone wrong?
   

Either way give the list a read, some others were Vine, Google Wave, Sparrow, and Sunrise.
