You just need to add ?share=1 to the URL, so you can read the page without login or register.
Actually it works with just, '? ' at end of url.
I just tested it and it works, it's more convenient than typing "?share=1". Quora link from search engine result or online discussion always has "?share=1" at the end of the link.
Was looking at github page and there is quora alternative now available.
quetre.pussthecat.org (one of instance)
Suppose the quora link is: https://www.quora.com/Is-it-true-that...
Then you can edit it to: https://quetre.pussthecat.org/Is-it-true-that...
Use libredirect/redirector to make it automatic.
Redirector pattern:
Example URL: https://www.quora.com/What-is-Linux-4?share=1
Include pattern: https?:\/\/(www\.)?quora\.com\/([^\?]*)
Redirect to: https://quetre.pussthecat.org/$2
Pattern type: Regular Expression
Pattern description: redirects all Quora urls(excluding language-specific and spaces) to Quetre
