First go to ‘Circles’ page. Create an empty circle and name it ‘Bookmarks’ or ‘Later’. Save it and it’ll be found as the last circle in the circles table.
Grab the bookmarks circle with your mouse and move it to the first place. Now it’s always the first circle on top, easy for you to click it when sharing something to it, and therefore it also shows on top of the Home page.
Now when you find an interesting post that you want to read or share later, you just share it to the ‘bookmarks’ circle. No-one else will see these posts but you.
If you want to share a post from there, it’s possible to re-share it but maximum to ‘Extended Circles’.
If you’d like to re-share the original post in public, click the word post at the top of the original one: for instance Paul Stickland originally shared this post.
Where can I find the ‘bookmark’ circle?
Go the ‘Home’ page, look at the top: There is the drop down menu for all your circles. Click open the bookmark circle and there they are, ready for you to read, delete or reshare.Google+
