Maybe Intel making its Fortran compilers for Windows and Linux has helped. Fortran Discourse https://fortran-lang.discourse.group/ is a recent, active discussion site, and Fortran-lang https://fortran-lang.org/ is a recent information hub. On GitHub the Fortran Programming Language group https://github.com/fortran-lang is active, creating a Fortran standard library and package manager.

That said, although I'm a Fortran fan and programmer I doubt its relative popularity has truly jumped so much in 1 year.
