Twitter has received a new round of investor funding that values the trendy micro-blogging site at 3.7 billion dollars, the company's chief executive revealed in a blog posting. The 200-million-dollar cash injection from venture capital firm Kleiner Perkins Caufield & Byers, comes just months after the company started its first serious efforts to monetize its community of 175 million registered users through special advertising products, according to dpa. The company was founded in 2007 and has now raised almost 400 million dollars in venture capital. Twitter currently employs some 350 people and its latest valuation makes it more valuable in theory than such media stalwarts as The New York Times, whose market capitalization is around 1.4 billion dollars.
