The fact that “The State of Fortran” is a paper on arXiv instead of a blog post actually says a lot about the state of Fortran.
Traditionally, these things were published in ACM SIGPLAN Fortran Forum (or on NAG’s servers for historical reasons). Arxiv is really natural, given the direction scientific and technical publishing is taking. This is a heavy duty language used by scientists and people like mechanical and nuclear engineers.
