Notice how this URL does not contain a hash (at the end). If you visit this URL, a hash will be added to the URL after the page loads. The hash value is some jumbled combination of letters and digits. What’s the purpose of this hash?
The idea is that when you share that page you will share it with the hash at the end. The visitors of the link you share will have their own hash generated to track their referrals. Medium will be able to see who visited the link that you shared, and build a tree of referrals (who the users you referred shared it with, who they shared it with etc). It’s a great metric to use in analytics when looking at user acquisition through social channels.
I hate this, I can’t tell you how many times I get a duplicate bookmark because I thought I didn’t have the article already in my bookmarks.
