I would worry about it.
It seems to bring the absolute worst out of people who are show offs, attention seekers and voyeurs. People go on holiday and put dozens of photos every day documenting their every move. People live stream a band they are watching instead of living in the moment and taking it all in. I know several people who have quite unhappy personal lives - relationship, debt etc but if you viewed them through their Facebook account you'd think they were living the dream. It should be called Fakebook.
I have an account which I use only for certain groups or when a band is playing but I never look at individual stuff. That's where you find out that bloke you haven't seen for 30 years but knew from school, is now a racist prick
