The author of this article should give Hardcover a fair shake, rather than admitting "I felt a bit of a social reading fatigue from Goodreads, Oku, and Literal, and since Hardcover also has a dedicated focus on connecting with others and explore their bookshelves, it was not the alternative I was looking for."

Yes, Hardcover has some degree of social component - but it also isn't a component that is in your face or that you have to use. Indeed, it isn't as dedicated to the social component (yet) as TheStoryGraph is... and yet the author highly praises TSG.

Full disclosure: I've been a paying Supporter of both TSG and Hardcover for a couple of years now, and I'm a Librarian in both systems. I'm also the staff-level Head Librarian at Hardcover. :)
