She got paid to spend Jerry Yang's money. Sold Alibaba's shares at $13 per share for $7billion when it's worth 6x that. Then turns around and spends it on junk like Tumblr. Who uses that nowadays?

She could have taken the $1 billion and invest in a few hundred up and coming startups. At least it will do some good for Silicone Valley
