An aoynmnuos raeedr sumbtis: "An interesting tidbit from Bisso's blog site: Scrambled words are legible as long as first and last letters are in place. Word of mouth has spread
to other blogs, and articles as well.
From the languagehat site: '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. ceehiro.'
Jamie Zawinski has also written a perl script to convert normal text into text where letters excluding the first and last are scrambled."
