Witnessing friends' vacations, love lives and work successes on Facebook can cause envy and trigger feelings of misery and loneliness, according to German researchers.
A study conducted jointly by two German universities found rampant envy on Facebook, the world's largest social network that now has over one billion users and has produced an unprecedented platform for social comparison.

I took the plunge, and have found it helpful in some ways. I don't post much, sometimes leave comments. Mainly try and wade past what for the most part 2 or 3 people clutter my page with. Because it is not a thing of prestige to me, my list of friends is limited and my site is very secure. But a lot of people do exactly what Christopher000 says, spend hours playing games, etc. When my mom went into the nursing home and I could not get a hold of my brother, I just had my wife post it in face book. He called the next day. Helps me keep in touch with some friends who have moved away. It gives opportunity to share your faith and prayer requests. Never understood why it was significant that people thought it was a sacrifice to give it up for lent. Might be because I don't celebrate lent. Envious, no we rejoice with those who rejoice. Most remarkable use have seen was on church visitation, my preacher was sure he knew where this family lived. He didn't. My son got out his iphone, found their address on facebook (why would you put that there) and punched it in to his phone and it guided us to their driveway with turn by turn voice directions.
I'm not a fan and think it is an enormous waste of time. I know people who post all day, every day, check in wherever they are, and are constantly on their phones checking to see what their friends are posting, etc...no thanks, I have better things to do and have had enough addictions...ha-ha.
