Facebook = Unhappiness?

I think we have all had our own ups and downs with Facebook... the cliche "Can't live with it, Can't live without it".  I commend any of you who have the ability to stay away from FB... I know some of you are "unplugging" and not using it on your phones, etc.  Heck, if you are one of those that doesn't have an account, AMAZING! (J deleted his a while back, but then recreated one for some video games he plays.  None of our families know about it, and he only has 3 friends, I think.  He and I are not friends).

So a while back, Lifehacker posted a link to this article (Can I just say I adore this website?  They have some great articles and how-tos... kinda a summary of what's great or needs to be known daily in the good ole interwebs).
In summary, it basically states that there was a study done, and they found that the more fb friends a person has, the more likely they are to be more narcissistic (changing photos and statuses more often) and be more aggressive when commenting.  The more friends you have, the unhappier you are.

Now, obviously this doesn't apply to everyone.  There are plenty of people out there that can separate facebook from their definition of happiness in life.  However, I can see how this is true in some cases.  There seem to be always be people who LIVE for Facebook, get angry if they aren't the first to know something, trolling, etc. 

I had to learn a long time ago that facebook is what it is... it's great to be able to keep in touch with people, post pictures, etc, but you cannot get your feelings hurt over every little thing there.  The horrible thing about FB is that you tend to think you know everything there is to know about a person from one website, and that isn't the case.  And don't even get me started on the people who feel a sense of entitlement and feel like you HAVE to friend them... grrr...

What do you think of this article? Do you see people on your friend's list that it may apply to?
