Not sure what I should be looking for, any hints? Also, the link doesn't quite go to the "first commits of the Go repository", should I be looking at those instead?

Edit: Here's a link to the first, legendary commits in Go: https://github.com/golang/go/commits/eef3fbb83ee0d654fbd3545...

I guess HN stripped the "after" param from the URL, breaking your link.
