By this I mean,finding what your looking for is clear preferably on the first page, the font is readable, the information is helpful ( as well as current) and given clearly without assuming a specific level of web savy. Dyslexics need visuals in all forms. For example, video with maps graphs or whatever helps to get points across. An opposite example would be a site with a small font, black on white, complicated pull down menues, or the worse being redirected to another site without notice. Whirlygigs, pulsating neon print complicated lettering used to convince the site that your a person not an andriod.
