This has been confusing for sure - most of the improvements for the language has been blogged at the Bucklescript website, since the Reason repo was only responsible for the syntax (and syntax has been mostly stable). So there is a ton of momentum hidden from visitors on the Reason site.

Hopefully that issue solved by this rebrand - a language should have a unified website for Syntax, Compiler and Standard Lib, and Blog Updates.

It's use is widening at FB, that's what I understood.
