Let's imagine my mother gets a new laptop and a new smart phone. My goal would be for her to be able to see my Google+ "Posts" page without having to log into Google.
From a laptop, without logging in to Google, it's easy to see people's public Google+ posts be simply navigating to their "Posts" page (i.e. https://plus.google.com/107770072576338242009/posts).
From a smart phone, however, again without logging in to Google, if you try to go directly to the same "Posts" page (https://plus.google.com/107770072576338242009/posts), you are redirected to m.google.com where you see a link to "Posts", but if you click it, you are asked to sign in with your Google account. This is odd to me. The posts are public; they should be anonymously viewable from a smart phone just like they are from a laptop.
A workaround for anonymous smart phone users to view Google+ "Posts" pages without logging in is to first navigate to the user's "Photos" page, such as (https://plus.google.com/photos/107770072576338242009/albums/posts) and then click the user's name (i.e. "Philip Durbin]") to get their "Posts" page, but this is a kludge. Is there a better way?
