The first step in accessifying a websites is to validate the (X)HTML markup. Then it goes on from there by using semantics as a foundation. But why is all that so important (to me)? You see, the greatest part of the internet that I can see is that it makes us all equal. Black/white, disabled/non-disabled, etc..., TCP/IP (the protocol) doesn't care about all that. And websites shouldn't care either.
