There are a lot of language designers in Coders at Work, but it's not "mostly". Language designers: Brendan Eich, Joe Armstrong, Simon Peyton Jones, Guy Steele, Dan Ingalls, Ken Thompson Not language designers: Jamie Zawinski, Brad Fitzpatrick, Douglas Crockford, Peter Norvig, Bernie Cosell Marginal cases: Joshua Bloch, L Peter Deutsch, Fran Allen, Donald Knuth which comes to 6/5/4. (Justifications for the marginal cases: Bloch does lots of Java library work, but not AFAIK a lot of language design, and the language itself certainly isn't his; Deutsch did some very important language implementation but that's not all the same thing as language design; Allen, likewise; Knuth's TeX and METAFONT are both, in their way, languages, but that's not primarily what they are.) I wouldn't call that "mostly language designers". (For the avoidance of doubt: I think a "Game Programmers at Work" volume could be extremely interesting.)
