"Bud the Teacher" is a wonderful and widely viewed education blog.
Many teacher blogs link to it, so "Bud" is able to influence a lot of people.
In a recent post Bud quotes Ken Burns, who says:
I'm in the memory business, and each time a person dies, it's a whole library of memories that leave.
Bud adds: I hope we're all just a little bit in the memory business.
All scholars and teachers are in the memory business -- research of all sorts is our link to collective memory and teaching is our way of bringing it to conscious awareness.
Progressive scholars contribute to that awareness through memory-gathering research and teaching, but also through communications in the public media and, like Bud, through blogs.
