Check out the wealth of discussion at TVO. That is what I will now be doing instead of writing.
EDIT: I’m going!! I’m going this Sunday to the conference! I can’t get into the first one, the lecture, so I’ll have to watch it later or try to stand outside. But I’ll be there for afternoon panel sessions. Hurray! (And thank you to the lovely lady at TVO who helped me when I got only error messages when trying to register, very much!).
