How To Share Google Reader Stories to Google Plus via Read Write Web
The article seems to borrow the idea by Scott Kingery, but could be useful to anyone using Google Reader and Google +
Google Plus is built around sharing, and one of Google’s best sharing services is missing: Google Reader. It’s the free RSS reader that lets anyone subscribe to any website’s feed, and it’s behind some of the most popular RSS client apps, like Feedly. But there’s no built in way to share articles from Google Reader with your circles on Plus. Fortunately, you can make one pretty easily. Here’s how.
These are the steps to add Google Plus as a service on your Google Reader. Once you’ve set this up, all you have to do to share an article is the bit in the last step.
What isn’t guaranteed, though, is how the post will be displayed (it may just be a link, or it could have an accompanying image + excerpt), and as Tumblr usually displays a bit funny on other platforms when sharing, it might not be a Tumblr to G+ solution.
Anyway, if you want to try it yourself, the instructions are here
