Come on, this is a terrible idea for steganography. Unless this catches on as some sort of fad, which (a) it won't and (b) even if it did it would be short-lived, then sending a message with its letters scrambled in this way would be the last thing you'd want to do for steganography. The whole po

Changing around the order of a list of items is a pretty cool way to hide information. You can hide about log_2(n!) bits of information in a list of n items. In the case of words, you can move around the inner letters as long as there are no duplicates. If you want to experiment with the basic

I'm not sure if this is novel, but it's new to me, and a lot of fun to brighten up our otherwise dull day. Some guys over on dgcchat have stumbled on a simple steganography method. What follows is their own words, but in an edited single sequence: === Ragnar:
