Bernie, I applauded the diversity of views and perspectives in the opening paragraph which supports most of your comment. I know first hand how hard it is to coordinate speakers in a conference. Some delegates are able to work out these potentially conflicting perspectives for themselves, others may need some guidance. I know this can be difficult but it would be good if speakers were able to be aware of the themes of other speakers, beyond a simple abstract, so that the presentations mesh better. Although it was presentations at SafetyCONNECT that sparked the article, the comments about diversity of presentations and thought applies to all conferences.
