I know that as I saw the link and "parsed it" in my head I've concluded "but it obviously goes to google.com", the real place where also I log myself in. Later, I couldn't have believed my eyes as I've typed such an address in the browser and ended elsewhere, wherever, I had to use curl to convince me that, yes, google.com/amp just invisibly redirected to the site and the page of the rest of the url, whatever the rest was.
