I am not so sure. They actually have negative earning, GAAP-wise, caused by a huge amount of stock based compensation and acquisition costs. Even with all these spending, Twitter is not showing any growth. Twitter will lose more engineering and product talents as the stock price goes down. They can't also use stock to acquire growth either. It's a dead spiral. Twitter has been leveraging Wall street goodwill and hype but I think it's the start of the end.
