As for my Google+ account: Google Plus isn't Facebook ⇒ Feel free to circle me if you find my posts/shares interesting, but I do not always circle-back all people. Some of my interesting posts are public anyway. If I circle you, you don't have to re-circle me unless you find my posts interesting! My activities have shifted from Facebook and Twitter to GooglePlus, because - in many respects - Google+ is much better than Facebook & Twitter!
