Ten Simple Rules for Writing a PLOS Ten Simple Rules Article

When I read the title of this article I laughed out loud-how many times has that happened to you when reading professional articles? Laughter is good whatever the context. When I started the series in 2005, I had no idea it would be so successful. This article, which I had no part in writing, only adding commentary shown in italics, is in my mind a celebration of that success. My commentary is simply to provide a historical perspective to explain some aspects of why the collection is the way it is and, of course, to make a few personal observations which, after all, is what the collection is meant for. Thanks to HD and AL for making this happen and for including me as an author (see Rule 4) and to all those that have contributed over the past nine years.
