Well, it's not all about that at least. Hamilton Nolan at Gawker:
Writing about yourself can be part of a balanced journalism diet, but it sure ain't a whole fucking meal. By plundering your own life for material, you are not investing in yourself as a writer; you're spending the principal. Soon, it will all be used up. There is nothing more painful to watch than a writer desperately grasping at ever less-important aspects of their own lives in order to make word counts, until they must simultaneously eat lunch and be writing about eating that lunch at the same time. It is the most small-minded interpretation of "journalism" there is. It is sad.
