I’ve posted some comments about both of those and other topics at my improv blog.
Just posted an entry about the first Improv Class. It’s over, but I wrote a few memories. See my blog.
I started up a separate blog for bits related 1) the Improv coures I’ve been teaching, 2) the Thursday Night Jams and 3) Performance Studies at EMU (classes I’m taking this fall). So, go check that one out too if you want to see what I’m up to. The link is http://improv.fedel.com/wordpress. AND It’s powered by wordpress, the same folks who made this cool blog software we’re using right now.
