building a whole new site from scratch

This is a video from fellow missoulian Hank Green.  His youtube channel is bigger than mine.  A lot bigger.  Okay, orders of magnitude bigger.  

In this video he addresses being contacted by lots of people suggestion "hank, youtube sucks, you should go make a new website that is better than youtube."  I thought his response was really good and could even go so far as to think about replacing "youtube.com" with "permies.com" in what he is saying.
