"LOL!" "that's so funny!!" What happened to genuine laughing?.....ah social networking

I think social networking is becoming rather ridiculous; people use twitter to tell the world what they are doing every moment of their lives, and we use facebook to post deep meaningful statuses so people think of us as wise and insightful. Yes, I am a guilty of this facebook crime (I will never be able bring myself to join the nuisance called twitter) but I am also well aware of how out-of-hand this whole social networking business has gotten.
We waste our time waiting for someone to log on to facebook chat so that we can talk to them. When we could pick up a phone or go out to lunch or to a movie with them. It seems now a days we have become afraid of the physical human being, hoping that we can use whatever computerized program, so that we don't have to be physically infront of someone. Some say it's to much of a hassel to call someone or to visit them. Others say that this way of social networking is quicker, this is true, however we must exercise our social muscles. We need to work our mouths and ears and become more accustom to have real in person conversations. I have noticed that due to the lack of impersonal conversation I have found my self caught up in awkward conversation with friends because we don't know what to talk about. It is not like I can ask so one,"What are you up to?" when they are standing right in front of me and I know very well what they are up to. Social networking sites are taking a toll on the classic casual conversation; a person can't say, "lol!" or "OMG!" to carry a conversation. Our conversations should contain dialogue of substance. We have to remember that we must listen to someone as they speak and digest the phrases that come out of their mouths before we start typing in our heads what we are going to say next. I feel like social networking is killing the common casual conversation, if we can't carry a casual conversation how will we ever carry a formal conversation? At a college interview we should at least be able to fake that we can speak eloquently. Overall I think social networking is getting out of hand and that it's resulting in a lack of communication skills.
