Please. I agree that our celebrity-focused culture is idiotic, and Linus has accomplished more than most of us ever hope to, but calling actors "idiots" is insulting. Most of them work hard just like we do (some harder), and are quite good at their job.
Remember, it's cool to affect a proud lack of knowledge in many areas ("football, what's that?") but to not know about famous people or things in computing is simply a sin.
It would be funny to ask someone who was affecting that something like "Then what have you accomplished?" See I could picture Linus being completely oblivious to celebrity, there's a seriously big deal that he came up with while he was busy not watching popular movies.
If the person saying "oh football what's that?" hasn't actually done anything really impressive then what are they doing if too busy to notice pop culture? Just living in a cave and staring at the shadows?!
After all, are you not entertained?
