This article is useless on Readup because You miss all the links. On iOS from Readup you don't even understand because no one is telling you that you can't read them. If Readup is just for essays and longreads, without links, you whould write it somewhere. Once I am logged in there is no page where to get what's Readup and what's for. Bill and Jeff, we have to talk ;-)
By the way, I wanted to suggest this newsletter because I love the digital garden concept and probably you too if you could opt in to see the links inside the page.
