Installation

RSS Share for Google+ and Google Reader (henceforth referred to as RSS Share) is a Chrome/Chromium extension, so yes, you will need to be running Google’s browser. If you haven’t already tried Chrome, you may be surprised by the speed and simplicity of the UI.
The extension can be installed from this page. It’s a simple one-click install that should operate like any other Chrome extension.

What it Does

The features, as described by the developer, are as follows:

“Share on Google+” button in Google Reader (Optional) Add Google Reader section to Google+ Show read and unread RSS items on Google Plus Choose if read items are shown Instantly share any link Google Reader unread count on Google Plus j/k key bindings for scrolling through RSS items on Google Plus Infinite scrolling for RSS items Click on title to refresh unread count Tree view of feeds

Usage

First, if you have any Google+ or Reader tabs open, you’ll want to fully refresh them after the extension is installed to make sure the page is rendered with the new bits included. In Reader, you’ll now see a Share with Google+ option at the bottom of each post.

which will bring up the sharing interface familiar to any Google+ user.

That’s nice and all, but RSS Share actually has another trick up it’s sleeve, and it’s a good one. If you open up your Google+, you’ll see that you’ve now got a list of your feeds in the sidebar, under your stream options.

Clicking on any of the titles will bring up the feed in Google+.

Unfortunately, I have yet to find a way to post entries from Google+ to Reader, but I suppose when you consider that those items are in an entirely different format from RSS and have security and other considerations applied, it makes some technical sense.

Conclusion

It’s been this author’s experience that many similar extensions tend to feel clunky and tacked-on. RSS Share for Google+ and Google Reader is the first I’ve found that integrates seamlessly, and feels like it belongs in the base applications. There are times when such things seem useful at first but quickly get forgotten, but RSS Share is something I’ll be keeping around for a while.
