What is a Blogette?

 I wanted a way to distinguish shorter posts that are part of microblogs posted to my Instagram account. After pondering over it for a while, I recalled a small blog that BJ Lifton started shortly before she died. She did not write much on it, after starting it. But I cherished what she did write. I also loved that she called it a "blogette." So much more elegant and so much more her than "microblog" or any other designation. I'm using the word here, with credit to her, in her honor and memory. Who was Dr. Betty Jean Lifton?
