Amazon URL contains "tag=aphackernews-20" query param after following the shortened URL... does Hacker News rewrite Amazon links to include a Hacker News referral tag?! Here's the URL without all the extraneous stuff added (though maybe it will just get auto-rewritten, time to find out I guess) https://www.amazon.com/Victorian-Internet-Remarkable-Nineteenth-line/dp/162040592X https://www.amazon.com/Victorian-Internet-Remarkable-Ninetee... No, now I understand what "aphackernews" is, it's "ap" short for "alexpotato".
