From TechCrunch..."from two separate people close to the negotiations: Google is in late stage negotiations to acquire Twitter. We don't know the price but can assume its well, well north of the $250 million valuation that they saw in their recent funding."
"If this is accurate, it’s a brilliant deal for Google - the value of Twitter is only going to go up over time."
Also, this would be a great deal for the 20 or so Twitter employees as well as Twitter venture investors Spark Capital and Union Square Ventures. Google sure loves to overpay for companies especially when that Company was only recently trying to raise a funding round. It will be quite sad to see Twitter become one of the many subsidiaries lost inside of the Google Machine.
