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:
Aoccdrnig to a rscheearch at an Elingsh uinervtisy, it deosn't
mttaer in waht oredr the ltteers in a wrod are, the olny
iprmoetnt tihng is taht frist and lsat ltteer is at the rghit
pclae. The rset can be a toatl mses and you can sitll raed it
wouthit porbelm. Tihs is bcuseae we do not raed ervey lteter by
it slef but the wrod as a wlohe.

Ragnar (2):
I suppose, for those that don't have encryption, a proggy can be
developed to change around words (keeping the last and first
letter the same) in an email before sending, based on this
research.  :)

Ken Griffith adds:
Taht wulod be an execlenlt way to sned emial msesgaes in palin txet taht
cnnaot be dteetced by ehceoln.  One culod tlak aoubt bmbos, trerroitss and
suftf lkie taht wiohtut trgigreing the fagls.
=======================================

No work on the original research though.
