A personal commentary is the writing of a personal experience or opinion of the author from his own point of view. The commentary is a brief work more suited to a literary journal, newspaper or blog than a book, and it is journalistic in tone.
A personal commentary may be written on any topic as long as the writer can present the work in a professional manner. The commentary differs from the personal essay in that it has a more news-like tone. Potential topics for a personal commentary include travel, entertainment, food and drink, politics and relationships. One example may be the author's personal view on a recently attended political rally. To keep the work in the realm of "commentary," rather than "essay," it is important to focus on the facts and opinions about them rather than going into small details about the event.
