Handicapped Bloggers

The other day I was looking at the comments section of my blog and I noticed that in the word verification there is a little handicap symbol that is an audio clip. I pondered the audio clip and then I clicked on it. You should do it, it was fun! It started rattling off numbers to me. I then discovered that if you type these numbers in instead of the letters it works! Glorious. But I still couldn't figure out who needed an audio clip. I thought it would be for blind people, but I didn't know how blind people used the internet. So I asked Ken. This is Ken's answer. Thank you Ken for answering my question and putting my mind at ease...you should click on his answer and read it. You just might learn something new. I sure did!
