1) I spent several hundred hours chasing down some topic I like, such as ethics, philosophy of science, global warming, The Crusades, whatever
2) Joe Blow the famous internet guy gets a bug stuck in his butt about the same topic -- perhaps he saw it on Oprah or read it on a discarded cocktail napkin. Who knows.
3) Joe does a TED talk, writes a blog, or some other way tells us his deep thoughts, most of which sound like a spin-off of The Matrix. Very cool. Very shallow. And without any historical context.
Everybody oohs and ahs and talks about how cool Joe is.
I'm not saying that has happened here. I'm not saying that I have some kind of deep insight. God knows I'm Joe to some other schmuck. All I'm saying is that reading blogs or watching videos in which people say trivial things while others applaud is getting a bit tiring. I love everybody participating in a debate! But I wish there was some way to rank the content of the material so I wouldn't have to go over elementary material -- many times arguing with people who don't know better. Talk about a waste of time for everybody.
Some kind of difficulty-rating system for internet material would be really cool. Save us all a lot of time on mis-matched conversations.
