Dyslexia in IT?

I was just reading the discussion “How prevelant is Autism/Aspergers Syndrome in the IT field.” and it made me ask the question yet again about how prevelant dyslexia is in the IT field?

I just recently graduated from CIS and I can say that 1/2 my class was diagnosed with dyslexia. In places I have worked (IT field-wise) it seems to be a common occurence, as well.

What do you think?
