Bad analogy on my part. No, I don't consider me his boss.
I was trying to give an example of someone on the delivery end of an established expectation. The employer->employee one is simply the most common to go to for an example.
I consider myself in the group he has made commitments to that he has failed (many times) to meet his stated delivery expectation.
That is the crux of my frustration towards him, and I don't think that frustration is (as Neil said in that article) is in any way because he works for me, or that he's "my bitch." Just that he over promises and under-delivers.
In the end I'm sure I'll buy the book, read it and based on his past works quite enjoy it. Doesn't mean I don't feel annoyance at him as a person for the way he sets that expectation and then when he fails to meet it.
As I said in the message you replied to (yet didn't quote) had he not set an expectation (let alone continued to set it and not meet it a hand-full of times over the years) I wouldn't feel any frustration towards him over this. I don't care if a book takes as long as it takes; my frustration is entirely in how he handled the expectation of it's completion.
