Intranets “One major UK corporation which is notorious for having inaccessible public web pages, is suddenly spending considerable sums on making their intranet accessible - for no other reason (as far as my informant could tell) than because they'd realised they risked some rather high-profile court actions by employees.” -- Alan Flavell.

Intranets “A member of staff could (we hope not, but it happens) lose their sight (or 'gain' some other disability) at any time. Equally, you could employ someone. If this happens down the road, you could have a massive problem.” -- Anonymous Contributor (Intranet Forum)

"Why would you care about standards support? You can code things that work in IE, and that's fine - nobody really uses anything but IE, coding for all browsers is a waste of time. Now what would you rather have a development team doing, working on standards support or adding in cool proprietary things, like 3D powerpoint-style page transitions, that will make their web "experience" that much better" -- unnamed Microsoft employee
