Saudi billionaire Prince Alwaleed bin Talal has taken a $US300m stake in Twitter. But that's small change to this guy, whose wealth is estimated to be just below $US20bn.
"Our investment in Twitter reaffirms our ability in identifying suitable opportunities to invest in promising, high-growth businesses with a global impact."
Alwaleed also holds a 7% stake in News Corporation, Rupert Murdoch's giant media enterprise. The man has some pretty heavyweight connections, then. [The Guardian]
