The word Go is far too overloaded in the English Language, and the difference is not always clear from context.

This title could easily have refferred to the correct meaning of 5 weeks with the programming language Go, 5 weeks playing and studying the game Go, or in a slightly colloquial usage, 5 weeks of constantly doing things and going.

And those are just the meanings that make sense in this context. It is also a verb with a wide variety of (related) meanings and forms a command part of a command in multiple computer languages (T-SQL uses Go, goto is infamous in Basic, etc).
