Many of you are familiar with RSS feeds, which are a convenient way to subscribe to syndicated content from around the web. All this information is aggregated and delivered to a single location, such as Google Reader, for easier and more efficient consumption.

In Google+, keeping an RSS feed of someone’s public Stream can be quite useful. Because Google+ currently only allows you to view the past 250 posts on someone’s profile page, until that bug is fixed, RSS can be an easy workaround to archive that content. It can also be used to keep track of your own posts to refer to later, as well as a way to make sure you don’t miss out on anything fun, interesting, or important since there are limitations on viewing a Stream’s history. Furthermore, a feed reader like Google Reader is able to easily search through that information, which is very useful if you don’t want to bother with yet another workaround for seaching G+ posts.

Previously, the majority of people who wanted this functionality probably used PlusFeed, which was created by Russell Beattie and served over 25,000 feeds per day. However, with the recent increase in Google App Engine prices, he was unable to maintain the service.

But don’t fret! Your fellow technophiles and G+ neighbors have already whipped together some alternatives.

Siegfried Hirsch optimized Russell’s open-source code and spawned PlusFeed2, which obtains an Atom feed of public G+ posts. Another instance of the original PlusFeed has been ported as GPlusFeed by Ted Kulp. A third option for syndication is Andy De Ruyter’s Plusr service, which provides an unofficial Google+ mobile or RSS page of a G+ profile. Lastly, you can use Matt Senter’s zipl.us, which also doubles as one of the many G+ profile link shortening services.

You can generate an RSS feed by adding yours or someone else’s profile ID number after the URL of each service. Your profile ID can be easily found by going to your profile page and copying the long list of numbers from your browser’s address bar, as seen in the picture below.

The opposite is possible too: there is a Chrome extension that will let you send articles directly from Google Reader back to Google+. RSS Share for Google Plus by Sebastián Ventura adds a Google Reader menu within the left-hand column of G+. Clicking on those feed items will have them show up separately in their own Stream. If you are looking to share links to Google+ from Google Reader without all the extra functionality embedded into G+, you can go into the extension’s options and deselect “Add Google Reader to Google+” and “Show Read Items on Google+”. That way, your G+ experience will remain completely unchanged while still providing the link in Google Reader at the bottom of each article to “Share on Google+”. When you click on that link, the familiar G+ share box should pop up.

Now that Google is starting to release an official public API (application programming interface) to developers, soon you will be seeing more robust and effective ways of manipulating, presenting, and connecting information between Google+ and the web.
