Watching Mark Zuckerberg testify to Congress was a bit like watching someone explain the internet to their grandmother.  At first, you see the Senators had some questions loaded to really kind of grill Zuckerberg on Facebook and privacy, but as soon as he starts explaining any facet of software, you can see the senators eyes just glaze over.  I don’t want to blame it on the ages of the respective senators.  I know plenty of older people who are more tech savvy than me.  But you can tell that the current generation of senators are a few steps behind in understanding the basic business model of social media.
