Programming for the Blind (Score 5, Interesting)

Until I witnessed a 100% blind person using a computer, my
understanding of the problem was very flawed. With the
monitor turned off he could browse web sites, read/write
email, and puzzle through popup error messages. He used
a text to speech software package that read to him faster
than I could listen. The package also provided an interface
for configuring a huge number of custom hotkeys which he
programmed and used extensively. The way his brain adapted to a
sound based interface was amazing. I've never seen anything
like it.
