5 Ways to Save Google Plus Posts for Later ReadingWhile you're browsing Google+ on your computer, you may come across a post which you might want to read or share later. There are a few ways you can do this using Chrome Extensions and other service tools. There are likely to be similar methods to use the same services in Firefox or IE.1. Read It Later - Service, Chrome Extension + Mobile App
This is my personal favourite because it syncronises with the ReadItLater service across my desktops (Chrome) and all my devices and now has over 300 apps. https://chrome.google.com/webstore/detail/bbabbdijmipkeilehcnbopedgbjejbmb2. Evernote - Sharing to an Evernote Circle
I learned this technique from +Chase Mann
in the early days of G+ and I was already an Evernote user. If you want to save a post for more than just reading it later, you can do this by sharing to a circle which only has a 'user' you've added which is your evernote email address. For more detailed instructions, see Chase's post. https://plus.google.com/104226133029319075907/posts/TT2NMtK7zWg3. Favorite Posts for Google+
This is a Chrome Extension that adds a favorite star to each post in a G+ stream, just click the star to add the post to your G+ Favorites. To access the full listing, a Favorites menu link has been added to the left sidebar to access your list of favorite posts.https://chrome.google.com/webstore/detail/kbhljnodjcehoonoejjpjnifgkkgjiec4. ReadLaterFast Chrome Extension
The last Chrome extension I tested was ReadLaterFast, similar to ReadItLater, but can be used either in Chrome only mode without sync, or by syncing to a Diigo.com account.https://chrome.google.com/webstore/detail/decdfngdidijkdjgbknlnepdljfaepji5. Share to Empty Circle
If you create a circle without adding any users to it, you can also share posts to this circle to save for later. You would still have access to the circle from your mobile apps if they are configured to display this circle.
There are probably a dozen more ways to save posts from Google+, but these seemed the most obvious to me.
