It's funny the market effect, if you're, say, John Dolan, it's vastly more time efficient to spend an hour and a half talking to your buddy and get paid for it than it is to spend many hours researching and writing a 1000 or 2000 word essay on a topic that nobody wants to pay for. It's kind of interesting the psychology here: people will pay for things which take hours out of their week, but won't pay for the thing which takes 3 minutes to read, even if the 3 minute thing contains more information. From my perspective; the denser information is more valuable!
