Broken link on the postrank-labs org page

[Nolan Evans]

Just noticed this, it's www.goliath.io, which is a defunct page, I assume it should be goliath.io or the page it redirects to postrank-labs.github.io/goliath/

I can't update it @dj2 or @igrigorik will need to.

Thanks for the heads up - fixed.
