Twitter Raising New Cash At $250 Million Valuation

"Twitter, which just recently turned down a half billion dollar acquisition offer from Facebook (albeit to be paid mostly with Facebook stock), is dipping back into the venture capital market, we’ve heard from a source with knowledge of the deal. They’ve signed a term sheet with at least one venture fund to raise a new round at a $250 million valuation. We are still gathering information on how much they’re raising and from whom."TechCrunch
