Being a good web citizen
Ten years ago I had a long email conversation with someone who was blind. He had bought one of my books and was using one of the example programs to write a better screen scraper for web sites than the one he was currently using. This made me realize how important it is to test our web sites so that everyone has access to them. I periodically use the text only web browser Lynx to test my sites. BTW, if you are in a hurry looking for real information on the web, you might try Lynx: sometimes plain text is better and faster, if sites are well designed: keyboard-only web browsing :-)
Spend a little time getting used to Lynx, and you may like it as a fast alternative for web browsing.
