Thanks for the easy to follow getting started for Golang.
I did find an error in the first blog post when following the steps on a Mac.
You have the command cd $HOME/go && mkdir test - This creates the new directory, but does not place the developer in the "test" directory which means those following along will likely create test.go in the "go" directory and not the test dir which is where you need to be in order to follow the rest of the steps as written.
Looking forward to the rest of the series.
