Aggregation Is Invisible In Google+. Thank Goodness. Louis Gray | The Google+ Project |
While I once was a major proponent of aggregation products that pulled from many corners of the Web, the value downstream is vastly diluted, and adds to noise.

In posting to Google+, it´s not about pulling from somewhere else, but adding direct value. Photos, video, links and location. That´s it. No aggregation to be found.
