Alas, I looked a little closer and it looks like the author used "awesome" because it followed in the footsteps of "awesome-python" which itself followed "awesome-php".
Therefore, the author's usage of "awesome" is simply a homage and not an adjective of significant semantics. (Unless the word "awesome" is constrained to mean "the libraries exist" which is amazing because Golang is only 4 years old. Imo, this is too low of a bar to signify as "awesome.")

I'm not really a great fan of github, but it's hard to deny that it is one easy way to facilitate and mediate contributions.
Spam sucks.
