I used to have long conversations via text. Some friendships existed primarily via text. The move to touch screens destroyed that. It just doesn't work for some reason. Nobody wants to have a long conversation using their phones. I'm not sure if it's due to the keyboard per se. I think it's more because you take the phone with you everywhere rather than sit down specifically to have a conversation. I'm not going to just keep talking forever throughout my day, so without a special time and place, it just stops altogether.
