When telephones are introduced for the first time and became affordable so everyone can have one, they were used like people were addicted to them. Than when mobile phones came, we had this same criticism. Why should I have cellphone with me all the time?

Now we have smartphones, it have cellphone in it that is so passe :) and SMS?! but there is something new, Twitter, Facebook, Instagram, Foursquare...

Those are just a new ways of communication and yes, we are overusing them until we are bored with it and after some time, we are going to forget them, like we did with the radio.
