This is how you make decisions quickly: "Fuckit, youtube is the biggest video site, gmail is the biggest mail server, and people have accounts on there! What's Facebook got that we don't! From now on errybody gets a Google+ account. Want to post on YouTube - bam, there's your real name. Do you have a gmail? Now you have Google+. Let's see Facebook compete with that! That's it, decision made. Go!"
I think on the surface this kind of a decision is a fantastic quick, touch decision, and one that fast-moving, risk-taking, companies can quickly try and implement. Unfortunately for Google, sometimes making tough decisions quickly is the wrong kind of quick.
