Restart thanks to Brazil

Well, it's been an inspirational trip here to Brazil. Visiting UNESP in Marilia and a conference here in Joao Pessoa. I'm heading out today, but I'm now convinced that I should pick this blog back up. I'll be posting my talks on this topic here, and perhaps we should start collecting other resources on the topic. I also think I should start writing up a syllabus. Jose Augusto Guimaraes was a great host and inspiration with his syllabi and commitment to this area. His students and colleagues are doing equally interesting work. I look forward to coming back.
