Yesterday I did something I rarely do. I participated in an academic seminar.   It was to mark the 40th anniversity of The Waffle, a radical youth movement inside the NDP.   Hardly anyone under 50 knows what The Waffle was, unless you have ever tried to organize an opposition in the NDP where it remains a scary ghost.   But it was a significant and almost unique formation of the 1960's in Canada.   Apparently scholarship on the 1960's is the hottest thing in academe these days.   Who knew?
