Well, awhile back I had the pleasure of reading an article about the deep rooted emotional experiences brought on by "Tweeting" (Verb that has recently
integrated itself into our vocabulary, It is from the base verb "To Tweet" which is the act of posting something on Twitter)
This article has stated that tweeting may make up for lost face time and may help us deal with our fear of dying. It has stated that while you are tweeting, and commenting and being commented on, you are never alone, you are never forgotten. This may ease our fear of dying, and more so of dying alone or being remembered. No one wishes to die and be immediately forgotten, and twitter prevents this, or so they believe.
I believe that this article is right, I believe that subconsciously people are screaming through twitter "Look at me! I'm here! I exist!".While if any Tweeters admit to this is unlikely, as it is a highly personal issue if this is correct, and this is simply theory.
