All you need to know about bleeding edge web design is encapsulated in the names of those companies - don't you think? Gaping void just about sums it up. I'd rather be informed and educated than inspired (or quite possibly frustrated) - but I'm an old fart, so what do I know?

Information (sources clearly referenced), clear illustrations, a title page which provides sensible shortcuts to the information I actually need, clear feedback system, regular updates, quick snd accurate without fancy stuff using up loads of memory and slowing down the pages I want, no pop-ups and no advertising . . . I think that covers what I want in web design. I suspect that it is not what web designers want to give us.
