Accessibility and Avatars

Today was the first time I considered that webpage designers were having to change the way they constructed webpages. Not because of a new method or web language, but because new technology can not read the current pages. That was a real eye opener since it may be a matter of time before public schools are required by law to have an accessable website. I was also astonished that so much was going on with the avatars and virtual worlds. If education goes to this format, teachers will have to be technologically literate and it will cut down on the face to face interaction. The questions will have to be asked: Which subjects can be taught with maximum effectiveness and no face time? and Would you hire somebody who earned a degree in this manner?
