The demo is enlightening, but the text is not telling to more important thing about dyslexia: The main problem is not the difficult to read (that is an issue of course) but the social implications for the people with this, when parents, teachers and pairs believes the kid can't read because is dumb or lazy. Self esteem goes to the floor and also impact in performance even in thing not related with reading.
So awareness that this is a real issue (and not that is lazy) and that the kid has to make a lot of effort to catch up is very important to help them have a better future.
