Today Google added G+ search to their newly opened Google Plus services.
First thing I did was search on "Google Reader" for signs of life in one of my favorite Google products. I'd recently put it on my death list due to long dangling half-finished work that encrusts Reader.
I found several optimistic signs, including this post: Tracy L. Crawford - Google+ - Google Reader Shares have a G+ link!.
In my case it's that the "options" drop down in posts shared by people I follow says "View this shared item in Google Buzz". If I try that it actually shows in G+.
Seems like some Buzz/Reader integration is underway. What you see may depend on whether you have Buzz enabled or not.
