In this case the idea is that if there is something needed by a special community of users useful for the rest of the community, get it in front of the rest of the community and piggyback on the momentum. People are doing things no one imagined they could-let alone would be interested in doing. However, many innovations on the Net have left some of our disabled friends out. For example, a video clip that isn't captioned can be very frustrating for a person who can't hear. Voice telephony would be wonderful if the person speaking could have their speech rendered as text for a deaf person to read.
People are only willing to spend time and energy that they think are worthwhile.
I'm intensely interested in trying to take all of the existing communication capabilities on the Network, make them all inter-work with each other, and as accessible as possible to people with a variety of disabilities. I want very much for it to be true that the Internet is for everyone. That is the slogan of the Internet Society, and we all know that that slogan isn't true yet. That's our goal. We have a lot of work to do.
