For those unfamiliar with accessibility issues pertaining to Web page design, consider that many users may be operating in contexts very different from your own:
	points 1, 2,3,4 all apply to users of speech output devices
	Blind users cannot see links, read text or relate to pictures – spatial problems are some times difficult, maps and the like. A mouse is useless to a blind computer user and ythe last point, many blind users make use of an old browser as they tend to work better with the old but still expensive screen review packages. Lynx is a common text only browser.
