I've been teaching an informal course on Gamemastering since last year at my university, focusing on Social Contract and Creative Agenda (GMing tasks, coherence, the Same Page Tool, Lines and Veils, etc.). I also cover material from Robin's Laws of Good Game Mastering and the Gnome Stew Books (Never Unprepared, Odyssey, Unframed, Focal Point). For the Big Model bits, I'm mostly basing my curriculum on the Big Model wiki, which hasn't been updated for a few years. I'm also familiar with Ron's essays on the Forge and the posts on Vince's blog.
I'm hoping to expand my course material into a video series, and would like to ensure my material is current. Has the discourse on the Big Model evolved since the closing of the Forge? If so, are there better references for the current state of the Big Model than the Big Model wiki? I'm happy to do any amount of research if pointed in the right direction.
