Amn't. Since you called me on it I had to check and see if I'd made it up or not. Apparently not. I only use it when I need sleep. Anyway.
I also like 1, primarily because it seems more elegant. Your assertion that the content would be redundant is an interesting one. It would be, in the sense that the content occurs in the body of a post. It wouldn't be, in the sense that it is a way to access and re-present portions of the primary content in a way that doesn't semantically or structurally privilege that content in its initial context. By which I mean, more simply, it enables us to focus on specific, contextually valid, elements within the content of a post without elevating those elements to the status of a post. Or: a quote in context is subservient but, since we're working with a database, if we later wish to collect all quotations or to reuse specific quotations we can do so without disrupting the structure of the original post in which they occurred. I hope at least one of those explanations was coherent. The quotes remain redundant but the redundancy is justifiable.
I prefer to make all entries for one day as one post. I prefer not to interrupt the flow of my thought with additional posts for each facet of my thought I suspect will have future relevance. I feel that the greatest strength of a tool like WP is it's flexibility. It isn't a full blown CMS and I don't want one. It is an excellent tool for manipulating sequential textual and hyper-textual thought. I use to use it when it was beta but stopped. I've kept a diary in a plain text file for several years now. I don't want to change how I enter information but I would like more options in how I manipulate and present that information. I'm sorry it introduces redundancy but hope the functional and philosophical explanations of that redundancy reduces its repugnance.
Quotations are just one example, anyway. Story ideas, whatifs, comments on wine, bourbon, women, work, and music are all fair game. Say I write an idea that isn't a plot but could add texture to a story, e.g. "genetically engineered mice keep the floors free of crumbs but, because they are unable to evacuate waste outside of a special pheromone treated 'nest,' do not contribute to the mess." And a few months later I write "he begins as someone who routinely turns gold into lead and only reluctantly leads the rag-tag group of rejects to victory." I'd want to tag both with something like 'story_stuff' because seeing all those ideas together one after the other might be useful. Redundant, yes, pointless, no. I need to sleep. It's 4am. I'm excited about this idea, though. If you are sincere in your offer of assistance I'd be more than happy for your help. If you can send me email through this site I invite you to do so.
Thanks for your help and suggestions.
