Looks like the m.facebook.com link is a bit less annoying, though it also has the Login/Join popover. On a desktop browser, reading public posts (and pages) is very painful, with nearly one third of the screen always occupied by the Login/Join popover that also makes navigation difficult.

Right, I was on desktop, but I missed that the link above was to the mobile version (m.facebook), which did not had the login popover, which is very annoying on the desktop version.
