Google+ profiles do not have RSS feeds. So how can you create and subscribe RSS feeds for any Google+ profile, which will let you add the feed to your Google reader and track all your Google+ profiles in one RSS reader?
Create Google+ RSS Feeds
Visit the Unofficial Google+ User Feed creator at plusfeed.appspot.com which lets you create the RSS feed for any Google+ Profile. Its very simple to use.
Lets say our Google+ profile url is
https://plus.google.com/110720484075426485909/posts
So we grab the unique long number for our profile
110720484075426485909
and add it to the url plusfeed.appspot.com and we get a url like this
This is a RSS feed url. Simply add this to your Google Reader and you can track all our Google+ updates.
Similarly you can change that with your Google+ number or that of any user and subscribe to the RSS feeds in your favorite RSS reader like Google reader. The titles and content render very well. Since you have a RSS feed, you can also add it to your blog sidebar using RSS widgets. [via NirmalTV].
