Twitter Raising $100 Million

Twitter may not yet have generated any revenue, but that doesn’t mean it’s worthless: The online messaging site is nearing a deal to secure as much as $100 million from up to seven investors, according to The Wall Street Journal. The investors are valuing Twitter at about $1 billion; earlier this year, investors valued it at about $255 million. Twitter is expected to have 25 million users by the end of 2009.
