Twitter expects to post at least $1 billion in revenue by 2014 based on its expectations on the growth of its advertising business.
The growth is twice as fast as what analysts predict, according to Bloomberg, which cited unnamed sources in a report today. Twitter, however, could change or miss its forecast, the report said.
The guidance would answer some critics questioning how Twitter would make money off of its 140 million users. The company has increased its efforts to lure in marketers to the micro-blogging service, which relies on its users blasting out 140-character messages to each other.
