Even if Twitter Is Profitable, Is It Worth $1 Billion?

So much for all those people who consider Twitter worthless. It may actually be set to make a profit this year. How so? Bloomberg BusinessWeek reports Twitter has signed $25 million worth of deals to make its content available to search engines. It also reports that Twitter has figured out how to lower its telecommunications costs. Whether those deals really make Twitter profitable is open to debate. But even if it were to be in the black this year, do the deals make Twitter worth $1 billion?
