Nothing like an article about Facebook written by someone who admits he hates seeing people, "waste time," on Facebook!
Regardless, I Find using Google+ is just easier. For example, if I want to change my profile picture, all my Picassa albums are right there (as well as phone pics). I can choose any picture I want and edit it right there, in Google+, and poof! New profile pic. I rarely change my profile picture in FB because, frankly, it's a hassle. Maybe not a huge hassle, but the process involves logging into Flickr (or Picassa or whatever), or finding a file on a hard drive, then going back to FB to upload or link the photo, then cropping it from there, then posting. It's always seemed like too much of a bother.
Same goes for Sparks. Rather than find an article on the Web, then copy the URL, go to FB, share it, yadda yadda... I just peruse Sparks (essentially Google News as far as I can tell), find something interesting and hit, "share."
And, of course, there's the invaluable Circles. I can finally brag to a selected social circle that I logged forty hours playing Call of Duty without revealing to everyone else what a total slacker I am.
Personally, I've never been a huge FB fan, but my move to Google+ has more to do with its superior design as opposed to rebelling against FB. So far, Google+ just seems more fun to me.
