"Ever wonder how many times your shared Google+ content has been seen? Starting today you'll see a new number on your Google+ profile or page: total content views. This number is the sum of your profile, post and photo views since October 2012, and you can choose to show or hide it via settings. Just visit plus.google.com/settings, scroll down to "Profile," and make your selection."
Arguably this is an attempt to bolster the popularity of the (really rather nifty) Google + platform.
Alternatively, it’s a move to make you feel unpopular or unloved.
Either way, unless you’re a website or a person of not inconsiderable popularity, I suspect most will leave this option switched off in the settings…
