Today was a big day for Twitter. The company released its first earnings report since it went public and it made more money than analysts were expecting, reporting an adjusted gain of $0.02 per share.

And Twitter’s monthly active users grew to 241 million, an increase of 9 million. But the problem that Twitter has always faced from the beginning is their users and how quickly they are acquiring them. Investors are paying close attention to user growth abroad, since they expect the U.S. market to become saturated.
