S.F. Documentary on the Intertubes

I've been sitting on some bookmarks of s.f. lectures and documentaries for the last few weeks, waiting till I had the chance to take them in. That day was, at long last, yesterday:

* At Cynical-C, Isaac Asimov on the Golden Age of Science Fiction;

* At Boing Boing, Neal Stephenson on problems of genre and criticism in contemporary s.f.;

* Via MetaFilter, A Day in the Afterlife of Philip K. Dick;

* And also via MetaFilter, the Sun Ra documentary Brother from Another Planet.

Enjoy!
