TWTR IPO

I am fairly confident that the TWTR IPO will be a success.  Why????  This is the perfect investment atmosphere for an IPO.  The climate is firmly bullish without regard for industry sustainability or fundamentals, and thus TWTR should flourish.  Janet Yellen gives a us promising hope that the QE train will keep rolling for at least another three months (and realistically probably longer), so I see no reason to be bearish until the great taper comes into play.
