There are several ideas for journals that I'm tempted to do, but the one I'd be most likely to use would be "Unfinished Tales." That's where I'd put all my orphan essays, the ones that I get half-done writing, get bored, and wander off, never to finish. I could put story snippets into it, as well. Not scenes from my book; just the little bits and pieces of stoy ideas that still drift through my head on the average day. Stuff I could write down that I would know I was probably never going to finish. Back in the 80s, when I kept an offline journal, that's what I did with it. It was home to a myriad of half-baked thoughts and stories that stopped mid-sentence.
I guess I have a certain respect for what readers I do have. I don't want to post half-completed entries, even if it is my journal and I can write what I want.
