Best part of Golang ihmo; first time I saw a language mandate it's formatting. Fast compiles are also nice, but not exclusive to Go (C, C++, OCaml, also compile fast).

I find it interesting that Google uses Rust. I know they work on Rust-based kernel code for Android. I'm curious to know if they also use it for networked application code, and why they picked it over Go.

Personally I prefer Rust over Go for it's types, and I never use it in big projects, so compile time does not bother me. But Google basically created Go for it's networked application code.
