Williams talks more about the classes and good times at University of Kansas at Lawrence, Silverberg worries about the rare minerals becoming more rare, and Kelly is once again talking about e-books.
I like:
"Maiden Voyage" by Jack McDevitt -- it's a prequel story to Priscilla Hutchins, the protagonist of his Priscilla Hutchins books, and she not only finds some interesting things on her first flight, but she starts setting a rule about them.
"In the House of Aryaman, a Lonely Signal Burns" by Elizabeth Bear -- a fascinating future murder mystery -- both for the future and the mystery.
