> Overuse of concurrency. People like to use the `go` statement wherever possible, and create overly-complex APIs with channels. Unless you have multiple events that need to be done in parallel, yet simultaneously needing to communicate between them, you should not use them in your package's public API. Let your package consumers choose when to make that call.

Agree. As much as possible, always leave it up to your caller on whether or not you want the blocking calls to run concurrently. Over-use of `go` as well as unnecessarily buffered channels are two really common anti-patterns with new Go developers.

And don't get me wrong, they're not breaking or absolutely terrible design choices, it's just that they're choices you typically wouldn't make after spending quality time writing apps with the language.
