>> It looks like it has become fashionable to write Go related posts as they sure get the attention on HN

No, not really. I filter for Go, Rust, Nim, and Dart on HN. Rust is the most popular with at least a post every day or two and Go about half that time or less. There used to be way more Go articles in past years. Some of the recent Go posts have gotten traction so maybe you're seeing that.
