Some speculation about a potential Google/Twitter acquisition
Here's my simple reasoning for why Google won't buy Twitter: Twitter won't sell.
Those who decide whether Twitter goes to Google pretty much come down to a handful of folks: Founders Evan Williams, Jack Dorsey, and Biz Stone, with COO Dick Costolo and Twitter's investors and other Board members (Fred Wilson, Peter Fenton, and Bijan Sabet). I know most of these guys well enough to say this with confidence: They don't want to sell, and even more importantly, they don't need to.
Now, sure, Google can write a ridiculous check, and perhaps, that might sway the key folks (management). But I doubt it. Why? Because nearly all of them have already sold a company to Google - Blogger (Evan and Biz) or Feeedburner (Dick). And, well, they didn't stick around, did they?
