Edit Nazis

Why do so many bloggers detail their edits?

Correct me if I'm wrong, but this is an online journal, akin to a diary. This doesn't make me a journalist. I am bound by no code of ethics here. I write this primarily so that I have a record of my thoughts and feelings about the b-school experience. If anyone can relate to what I'm writing here (and I don't flatter myself that they do), they are welcome to read it.

Are there "edit nazis" out there reviewing the blogs, ready to pounce on every edit that hasn't been noted by its author?
