There is a simple formula for determining how readable your piece of text is. The formula can be found at
http://en.wikipedia.org/wiki/Flesch-Kincaid
it would be nice to have in Scrivener (beside the number of words and chars in the footer). Personally I would get at least as much information by knowing how readable my text is, as from knowing how many characters are in it.
This has been suggested (and rejected) before. I don’t really like formulas that are supposed to determine something as subjective as “readability”, for one thing; for another, Scrivener knows nothing about sentences and syllables. The latter, especially, would be a massive undertaking.

“To boldly go where no one has ever buggered up before” is a class line appreciated by an English speaker.
A program which measures appreciability is measured by the lowest common denominator.
I wonder which nation that is ?
Lets go for class writing for people that read and buy books rather than those who are read to.
It may be a shrinking audience but you can afford to buy a round of drinks for them.

Though cf. my rant in the Writer’s Block forum recently, quoting “Mind the Gaffe”, about why there is no such thing as a split infinitive, and thus “to boldly go” is perfectly fine.
