Facebook is profitable, Twitter isn't. But you're right, just perhaps not in the way you mean, Twitter isn't going anywhere. $11 billion market cap is nothing to sneeze at, however it's lost about that much value in one year. So is it a going concern? Sure it'll probably still be here in a year, but my confidence level beyond 12 months is weak at best. Five years? shrug 50/50. If it's not profitable, how does it continue to function at a certain point? At what point is it functionally on life support?
