This week's interview guest is Curtis Chong, Director of Technology for the National Federation of the Blind, the group that is suing AOL over access for blind users. Chong is a bona fide expert on computer use by the blind; he's blind himself, and before he took his current job he spent 17 years "...with American Express as a designer/consultant, providing technical support for mainframe and mid range communication and operating system software." So ask away. One question per post, please. 10 - 15 selected questions will be forwarded to Curtis Tuesday. Answers will appear Friday.
