I've seen debates about whether it's possible to monetise Twitter. 
Operationally, it's an issue if they fail financially, but I don't think 
the investment in setting up an account is large enough to worry about.

Counter-intuitively, I've probably seen more subscription-based services 
fail, than free ones.
