I think they are going to post these. But I also think that essay "The Power of the Context" is available online. Did you even try to type this into Google? I just did and the pdf seems to be the first hit ...
I'm glad you mentioned it. There's lots of evidence (even from the emails I've been getting) that most people might be skimming even sentences and guessing, rather than actually reading the words.
