I think it's a big glorified support group for the verbally incompetent.
No, not "challenged".
I've evaluated some of the people I know from both RL and FB, and I am getting quite confirmed that the Facebook is for people who want to be able to communicate and be together, but can't do so just as well because of their lacking communication skills in real life.
I just understood that the friends who most have anything to say (and have the ability to tell it) don't bother with the facebook.
The rest of them - many of whom I wonder why I keep them as friends in the first place - are active in facebook, although they are just unfunny and meaningless in their communication in the real life. Perhaps they're nice as humans, have good qualities unrelated to communication, but it's all the same. Ok. Some of them are great. It's just that I have to utilize endurance tactiques to withstand the situation of talking to them.
Pretty much the same as what you have to utilize to withstand my long yapping in this internet forum. No, I'm no good with the internet forums. I think that's quite clear.
In any case:
I think the key word is communication.
Those who are really good with it in real life, don't generally bother with the facebook.
Only a selected few talk of heavy facebook users talk of anything else than the kind of porrige they ate that morning. Most of those people won't speak of anything more interested in real life. Their instant messaging is weak, their communication sub-par. Pictures of kittens anyone? The daily weather?
Facebook, along with rest of the internet, might lessen the gap of advantaged and less advantaged people in communication, but so far the results don't seem promising.
Then, facebook is different from people on the internet in general. Many people on the internet seem to have important and interesting things to say. I don't think many active people on the internet make very lively conversationalists, though. Perhaps some do. It's ok. You write better than I. We can live with our differences, and mostly have a mutual respect and enjoy for what we have.
I love the internet for many reasons.
Still, facebook isn't one of them.
I can't understand that more people don't more loudly tell how much it sucks.
