Opinion of Daniel K. Schneider: EdMedia is a major conference in Educational Technology. It participation mix (researchers, developers, and users) guarantees an "openness", where anyone that has a good idea or did create a nice design (and can write) is allowed to present. E.g. this conference is often used to present new artifacts and concepts. However, both audience and enthousiasm seem to have declined over the last 10 years, e.g. I could compare the 2002 and the 2012 edition which both took place in Denever. Or is it just the young generation ?
