There have been a few developer groups like Suckless. 2f30, cat-v or bitreich for example. For the most part, they seem to have been part of a Unix or Plan9 tradition, advocating and setting an example for what the so-called "Unix Philosophy" means.
Does anything like this exist in the Scheme/Lisp space? A group of people developing free-software utilities written in and for Lisp systems?
