I've noticed that Rust is in an interesting spot - it has a lot of overlapping appeal with various groups.

- C/C++ developers like it as an alternative for low level languages

- Functional programmers like it because of it's functional features

- "Cargo Culters" / "Hot Language" / "Flavor of the Month" followers like it, as it's in vogue at the moment (this is the crowd that has likely shifted from various web/API scripting languages over the last decade - (php|ruby|python) -> nodejs -> rust)

However, as the article alludes to, for the third crowd, Rust is just likely not a great fit (even if it has a lot of neat features and introduces some great concepts others may not stumble on of their own accord) when your implementation doesn't do much beyond web dev/API/scripting purposes.
