I don't think he offended Yegge in any way. It's a valid point to make when someone goes to make inaccurate predictions: you have to take that into consideration for future articles. But well, this is Hacker News these days.
For example, I am ridiculously bad at estimating how much time implementing features / fixing bugs would take. Most of the time I'm really off, at least by a factor of 2. Surely my manager should take this fact into consideration when asking me how much time something would take me when planning the timeline/schedule (he does, in fact).
Nope, that's a logical fallacy. Lots of people do it, yes. I'm guilty of it myself. But that doesn't mean that it's correct.
