A few sites remind us of our favorite CD encyclopedias. Not because it wasn't useful. He threw it away because the villagers thought the gods were crazy to tempt them with something so beautiful and useful, yet not provide enough for everyone. Consequently, harmony became disharmony as everyone wanted a chance to use the new tool. This is not our problem, or at least not the entire problem.
Many web sites created for education are indeed beautiful and useful.
And, although we struggle with issues of equity and access, our problem is that educators must justify their choice of resources. We have finite time and finite funding. We must choose resources that make the most effective use of their media so we can make the best use of ours. If a developer limits the use of a more capable medium to the constraints of a simpler one, he is misusing the medium. More sophisticated media are more costly-both in terms of the human and financial costs of creation, but also in terms of the user's learning time and hardware needs.
