I liked the what Dean Terry- wrote on his blog: "over the last couple of months is that I thought very carefully about deleting a tweet, which in turn made pressing send when composing one less casual than before. Everything felt more permanent. I’ve always wanted to create something that made people feel more tension when hitting “send” on a social network." We are a bit too trigger happy when it comes to socializing on the net. The air we breathe doesn't remember our spoken words but the internet does. Be careful.
