The tone about Grooveshark and Secret (update: and now Homejoy) shutting down sounds a lot like they failed but, did they?
Grooveshark was around for almost 10 years and was a pioneer in online music streaming. Secret and Homejoy made millions of users happy for a while. Both made something people wanted, and this is something only a small percentage of startups achieve. 
Is Blackberry a story of failure?
The lesson I see here is that success is subjective, transitory, nonlinear and mostly a state of mind we choose.
