I know everyone loves their high powered languages, but I'm afraid the author is right. The more developers, the more conformity you need. I'm doing a personal project in OCaml, and I absolutely love it. I like to think it keeps my medium size code base from ever turning into a large code base.
But Ocaml has so many features that two programmers can write in such different styles that it might as well be a different language. A team of maybe 5 people with a good attitude could probably work on the same code base. The same is true for lots of new languages like scala and clojure and even ruby.
Knowing what I know now, if there's a project that's going to have more than 10 people working on it, I'd hesitate to use anything except Java or C#.
