All you need is the Google+ user’s profile ID, the Google Plus User Feed URL and the RSS reader to add it to.
Following is the guide which will help you throughout for this process.
Copy the Profile ID of the person you want to add in your RSS list, Profile ID is a long series of number, which you can find in the address bar, when you open your friends profile.
Like my profile ID is 116010836063886273463
Add this url to your reader http://plusfeed.appspot.com/ and add the profile it at the end of this url. It will look like http://plusfeed.appspot.com/116010836063886273463
I am adding this to Google Reader, you do this for your custom RSS reader software.
