This was the first thing that I thought of. Jason calls the idea "Memory Hole", which is both a much better and much worse name than "Hibou".
But something about it always made me laugh, so that's what I called it.
Anyway, I'm so glad that someone FINALLY got around to building the damn thing! I guess the lesson here is that if you want something done, either do it yourself, or ... be prepared to wait a really long time. ;)
