Isn't that what we bloggists are doing? Even when not writing about ourselves the very fact of putting up a blog is a signal that we want to be seen and heard. Perhaps not for full-frontal revelation, perhaps only for those parts of our thoughts, observations, experiences, opinions, creations that we consider worth exposing to public scrutiny.
If this sounds like I'm leading up to a moral lecture about everything being vanity and illusion and self-indulgence....not at all! I'm all for self-exposure, as you may have noticed if you're a regular over here. This blog is my modest little streaking across the olympic football fields of the universe. Or words to that effect.
