Steven Aquino, writing for TidBITS:

Markdown has changed my life for the better. Not only is it easier to work with than graphical interfaces given the limitations of my vision, but it has caused me to embrace plain text for nearly all of my documents. No longer do I have to work in bloated word processors with toolbars galore, or worry about rich-text formatting. Discovering Markdown has been liberating in the truest sense of the word.

It’s amazing how the same markup we use to simply make our lives easier when writing for the web can be used to empower a writer who is legally blind.
