Chapter 1. Channel description seems to be wrong

[helinwang]

On page 17.

You can think of channels as an in-memory thread-safe message queue where senders pass data and receivers read data in a non-blocking, thread-safe way.

I think unbuffered channel (or buffered channel when it's full) is blocking - will be blocked until someone reads it.

That's true, that sentence could have been better written.

Thanks for confirming! Just want to create this issue as a documentation, in case other people have the same confusion as I do :)
