I did a search on the word dyslexia (my product is heavily used by people with dyslexia), and most of the top results were based on articles that did not use that word at all. They were more likely to be about autism, ADHD, or deafness. In fact, out of the 234 results, the word "dyslexia" only appeared 4 times.

Unless there is something magic going on that I don't understand, this seems like a pretty critical failing. I could do a google news search for "dyslexia" and I would likely get more relevant results (albeit without the authors' email addresses nicely formatted — I'd have to hunt that down on Twitter).
