Wall Street Journal: "People familiar with the matter" say that Facebook, Google and other tech companies have held low-level talks with Twitter executives about purchasing the company. Those discussions have yielded an estimated value for the company of $8 billion to $10 billion.
That valuation seems awfully high for a company that had revenues of $45 million, but actually lost money last year. However, it's hardly the first tech company to be valued so highly recently. Facebook, Groupon, the Huffington Post, Pandora and LinkedIn have all been valued very highly recently--leading some to wonder whether it's the start of another tech bubble.
