I prefer the look of Go or The Go Programming Language for branding so not fussed by the community name. The use of golang is just a hack but a useful one. It is used by other languages as well eg ziglang, rustlang when you want to distinguish from other uses of the word. Go has the additional problem of being too short but at least it isn’t c.

Golang is the defacto searchable term for the language. Even allowing for minimum length limitations in lemmy it makes sense to use the searchable name in any text you wish to be found. Consider how people search for answers to programming questions and how lemmy posts might be indexed.
