Can't read it because I'm signed into google but don't have a profile and google+ account. Google won't let me view the link without first joining google+. That's dirty!
While signed in to my Google account, I can't view the public google+ post posted above without being forced to create a Google profile.
Public google+ posts appear in Google's search results. Doesn't that mean that anyone should be able to view it, not just members? Isn't that Cloaking which is against Google's own TOS?
Yes - its meant to be a publicly available page. Not sure what's happening for you - I too am signed into google, but have not created a public profile nor do I have a google+ account.
