> compare how long it took a startup like Facebook to do it to Myspace to Google. It's still useful. The original comparison still isn't entirely useful in that context. It's as useful as saying a car going 85mph will get to 90mph faster than a car at rest. Google+ came out at 85mph, Facebook started in neutral while parked in a private garage. A more useful comparison would be how quickly Microsoft took away market share from Sony with the X-Box. Or the Zune vs the iPod. Or Android vs the iPhone... etc.
