backchan.nl is tool for involving audiences in presentations by
letting them suggest questions and vote on each other's
questions. backchan.nl is intended for conference or event
organizers who want a new way to solicit questions from the audience and make
better use of question and answer time.
One of the aspects of Backchan.nl that I'm excited about is the option to create multiple channels ahead of time. This will be a useful time-saver on the days when I have four consecutive classes and I want each class to have its own channel.
