Golang is often preferred as it's much easier to search for and no need to disambiguate between other things called Go (Chinese board game, 1999 film).
To be honest, I hate the name "Go" even for vocally conversing. It's such a common term that the context is completely lost with verbal communication so I'm often having to explain things in a long winded way. eg "It's programmed in Google's language named 'Go'".
Google probably should have just released it as "Golang" from the start to save a lot of trouble and confusion.
Google should have known better what's a good "googable" name. Golang is a good compromise
