Google has launched its new social networking site Google Plus some time ago, lots of people accepted an started using it. Google too adding new features so that it can compete with Facebook and Twitter. But stile Google+ misses one feature and its access to RSS feed to updates.
But now using a Google Chrome Extension you can get RSS feed update of any public update. Feed+ allows you to get RSS link of any public update, it also allows you too add that RSS to your Google Reader account.
After installing extension you can make a search for profile or directly add profile ID to get RSS feed. This extension is created using Google Apps Script and Google+ API. As Google hasn’t officially announced any official Google+ Profile RSS Feed so its an good alternative.
