Chuck Moore is one of my heros, and has been since those '70s that he talks about.
Try as I might, I have had a hellofatime using Forth (and now Factor) to get nontrivial things done. But I keep trying, because I find the philosophy so compelling. And I figure I'll learn something.
He has always considered Forth to be a 'personal leverage' tool rather than a programming system suited to a team. Similar in this regard to Lisp and J I suppose. The fact that he has never hired a programmer (!) reinforces this notion.
I wish him luck with his chips....
