Reading and Writing Systems: Conveying and Archiving Language

I had a really great idea just before falling asleep the other night, but I was too tired to get up and write it down. At least I’m pretty sure it was a great idea, although I just can’t remember enough of the details to confirm that it made any sense at all. In fact, I have no idea what the idea was about, and try as I may I can’t dredge up even the gist to see if I can reconstruct it for further evaluation.
