I've been trying out for the last few days - using Google+ as a content reader tool. With its new magazine layout on android devices, and lots of great circles to choose from, it brings content to me from people who are otherwise not available on other aggregators like Google Currents or Zite or Pulse.
I wonder how many others may have tried this. And if Google is able to get good no-nonsense content to Google+, it may attract no-nonsense users. It may not be able to compete with Facebook in terms of quantity of users, but can carve a good niche market for itself.
