The English of Martinez was sometimes somewhat difficult to follow, and Najman, who is an excellent scholar, is also an impresssive fast speaker, adding explanatory parantheses along the way. I must admit, however, not having English as my mother tongue, that I would have been greatly helped if there had been some handouts, giving the main aspects of the arguments presented. This is not something experienced only in this session; by no way,- many presentations suffer in a similar way. But that is no excuse. Please; do start considering using handouts.And Torrey refers to previous discussion of the phenomenon on the blogs. I think Torrey is bang on target here, and I would add that handouts are also regularly the choice of some disabled attendees, especially those who have trouble seeing a screen. The fact is that you simply cannot predict the technology either; this year we had one speaker in the Synoptics section who needed an overhead projector, and only the front row could see the screen.
Hence I have to wait some time to have a fuller understanding and enjoyment of these important papers.
To speak for myself, it really helps me to understand, to follow and to concentrate on a paper if there is a handout.
