writing for no reader

Most of the time this is writing for no reader, isn´t it? Does it matter to me? Some days it does. Some days it would be nice to know that someone womewhere is reading what I put down here. That´s the thing about blogs you just don´t know if someone looks at it and who that might be. In a way I am writing for no one and the whole world at the same time. That´s a big nobody to address.
