Have you ever considered the fact that blind people might be reading your blog? What about the fact that if you have some of the spam authorization modules that require you to look at a picture and type what you see would stop any blind reader from ever commenting on your site?
I have resisted the urge to implement spam protection on my site. Even thought I get thousands of spam comments a week, I have been able to use some of the wordpress pluggins to prevent or at least minimize the nuisance of dealing with spam comments.
Word verification spam filter have always annoyed me. To be honest until I read an article about how blind readers are pretty much left without a means to comment on the blogs I had never considered that side of things. As the ones of you that have been reading for a while know I took an ASL class and I am very interested on the hearing impaired world… when I started my podcast, it was one of the things I considered… I never want to alienate any of my readers. However I never even thought of the visually impaired.
Most people with disabilities do not feel sorry for themselves and I believe we should not either. However, I believe that being considerate has nothing to do with pity. I think that we should all be aware of what readers we do have and make sure we are not alienating any of them.
