Web conferencing continued

Web conferencing may have uses in the educational world, but with the state of the current technology I just do not see it happening. Although, I have only attended a few education seminars/discussions the level of conversation, question and answer and participation is much higher than in a business setting. Most of the business conferences I attended were more of a dissemination of information rather than a question and answer. I am not sure the technology is strong enough to support a conversational type environment. It is probably part of the reason you have seen Podcast become so big you can review the content at your leisure and respond via any number of electronic ways. In fact the last quarterly meeting of my former employer was done via podcast and employees were given an generic email to send questions to with assurances of a response within 72 hours. Someone is going to have revisualize the technology and make it more effective before it can become an essential educational tool.
