Recommended: Marissa Mayer quote from "In the Plex" by Steven Levy

"If you look at the arc and growth of content over time ... In 1995 there were 3 million web pages on the web and they could be hand categorized into categories. Which was Yahoo.  At some point the content just begins to explode which means the directory model has to fall by the wayside because you can't categorize everything, all the way, all the time and that is what really gave rise to search. ... When content gets large you need to search.   But now the web  is so vast you need different organizing tools in addition to search in order to see different aspects of it.  I think that social is something really important there.   What content have my  friends written? Or people I know and respect, what have they written? What have they liked? What have they read themselves?  Those pieces help to make sense of this vast sea of information that is the web."
