Nobody does that. But for certain areas this is true and you should not ignore that.
Grady Booch once at an Eclipse conference:
"For those of you looking at the future of development environments, I encourage you to go back and review some of the Xerox documentation for InterLisp-D."
We all do, to a more or lesser degree. Lispers, in particular, are prone to it. I do it, and I've seen you do it too.
This isn't, by the way, a slight on you. Nor do I dislike you in any way. I do tend to argue with you a lot, but that's because I disagree with you, and I am of the firm belief that you can learn a lot by discussing subjects with people who disagree with you regarding them.
