ALGOL 68 failed not only due to bad documentation but also because it was simply too complex to fully implement in a compiler given the limited hardware resources and project management methodologies available at the time. The few organizations that did try to write compilers each ended up implementing a different limited subset of the language so it was impossible to share much with a broader community.
