The tl;dr is that the Baymard institute publishes something on Medium limiting its distribution, the UX for finding out what the institute has to say (if you cannot read the article) is - read some blurb on Medium, search for name of institute to find website, go to website and decide if what they have to say is useful for you - or in the case where you go through HN or some other commentary on the article reading the comments first before searching for site.
Yeah same. The content on there is a mixed bag, they occasionally have stuff worth reading but there's also a lot of junk. Incognito mode doesn't seem to work for me anymore if I do feel the urge to see what it says. I guess if I delete my cookies it would work but then it's just too much of a hassle. The baymard site seems pretty interesting though.
