I have been asking myself this question since I learned about blogs many years ago. Why publish what is essentially a diary? Why invite strangers into your innermost spaces? If you are writing for your friends, why don't you just call them up? As for myself, I am more voyeur than exhibitionist. My motto may have been, variously, "less is more" and, to paraphrase Chanel, elegance is refusal.
So I have no answer to my question. Only another question: Is some one out there listening?
