I haven't been longer than 15 minutes on YouTube - in total within the past 2 years. So certainly not representative for me.
"Representative for me" is incoherent. You're not a population; you don't have population statistics.

So yes, YouTube must absolutely be included. And it should be included as the second most-tested site.
