I know people are suffering with the demise of twitter. I don’t want to minimise their pain. But this is a life lesson for you young folks. Everything is MySpace and Napster. Everything is AOL and GeoCities. Everything is a Zune and an Amazon Fire Phone.

If it’s the first platform you counted on that died and let you down, it’s not the last.

@paco Good point. Of course, the #twitter failure seems to have many additional layers of lessons, e.g., the enormous concentration of wealth's ability to destroy infrastructure important to journalism, academia, and ultimately, democracy. And it has been destroyed on a simple, Caligula-esque whim.
