> So a world divided into writes and write-nots is more dangerous than it sounds. It will be a world of thinks and think-nots. I know which half I want to be in, and I bet you do too.

I'd disagree with "half" here because I can't imagine it being anywhere close to 50/50. I expect a power law distribution: most won't be able to write well. The ones who do will have a massive advantage, in the same way that those who can concentrate in our age of distractions have a significant advantage over those who can't.
