Where to deleted characters go?

Although many of these entries read as though nobody even wrote them, let alone bothered to edit them, there is a certain amount of re-reading and editing going on. In the course of this, the backspace and delete keys are used heavily. 

So, where do those deleted characters go?

The laws of thermodynamics would seem somewhat relevant here. If letters can be neither created nor destroyed, then am I really destroying them? Do they go into some sort of letter sink, waiting to be recycled (self-plagarized) later?

If a humorous sentence is deleted, do the characters go to live in the Old Jokes Home?

What about quantum effects? When I delete something here, does it show up in somebody else's blog in some parallel universe? (In reverse, this effect would explain why sometimes these entries look like they were written by somebody else not in complete contact with this universe.)
