As this program appears designed to interpret what you want to say based on actual, English-language words, it would be interesting to see how it would handle poor spellers. Personally, I am probably somewhat of a spelling nazi, as I cannot stand how inept some persons (seemingly the younger generation--get off my lawn!) appear to be at spelling. If this is released, I would imagine that poor spellers would either (a) be forced to finally learn how to spell (again, get off my lawn!), or regrettably more likely (b) be frustrated with the program and write off it's inability to correct their own deficiency as a problem with the software, itself.
FTFY.
