GerardM writes "Today the "Universal Language Selector" premièred on the English Wikipedia. There is a ton of functionality in there and it has a lot of potential. The one thing that may prove to be a game changer for people with dyslexia is the inclusion of the OpenDyslexic font.
Once people with dyslexia start to adopt this font, chances are that they can actually read/use Wikipedia. A lot of people are dyslexic; to quote the en.wp article on the subject: "It is believed the prevalence of dyslexia is around 5-10 percent of a given population although there have been no studies to indicate an accurate percentage".
The one thing left to do; let people know that Wikipedia has improved usability for people with dyslexia. Please tell it to the teachers, the parents and most importantly to all the people you know who are dyslexic.
NB it is also available for many other languages on many other Wikis."
