Communication in social media

I was looking on facebook and as usual people are chatting it up amongst each other, with all of the youth computer lingo and the LOLing. Happy go lucky people and the sad and depressed people. The thing that really bothers me about social communication and online communication is that instead of talking face to face with people, people are talking online and their social skills are suffering from this. To add to my hatred of social network are the people who have comments that are negatively possitioned toward others, if they do not like them then they probably wont have them as a friend in the first place. This is just a opinion that I have of social networks such as facebook and how foolish people are when communicating with each other, but say some things that in person they would never say to someone else.
