So, essentially, Quora is now expertsexchange, with page cloaking and whatnot? Good to know.
(I hope they won't remove this method now that it's publicized...)
They actually officially communicated about this method:
Open any Quora URL. If you come across a Quora link
anywhere and you want to read it without being asked to
join Quora, you can add the text "?share=1" to the end
of the URL.
Nope. Even if this promise were to hold true, I have no intention of supporting such scammy tactics as content cloaking (which I would by implicitly supporting the company which engages in them, thus validating it).
