Unless you're in an industry that depends on it for PR, like entertainment.
I've actually worked on these sort of campaigns, you never just rely on a single platform and pray for traction.
More to the point: investors with irrational expectations are not the kind of investors who deserve to have their expectations met.
They are if the profits were greatly overestimated. Paying a billion for a dollar of profits isn't smart. Not to mention, Twitter isn't profitable. (They lose half a billion dollars a year.)
About a month ago I said I'd find Twitter a possibly reasonable buy at a third its current valuation [1]. To make that work, a lot would need to change. And Twitter's current investors would surely lose.
