I really like these collections - here are some of my thoughts on the stories in this volume that stuck out in my mind (wow, it's hard to say much about short stories without giving spoilers)
Even the Queen by Connie Willis - there was a lot of humor in this one, I liked it a lot.
Two Guys From the Future by Terry Bisson - clever time travel story
The Coming of Vertumnus by Ian Watson - pornographic vegetable portraits!
Grownups by Ian R. MacLeod - very weird and creepy
Graves by Joe Haldeman - blah
The Last Cardinal Bird in Tennessee by Neal Barrett, Jr. - I didn't get this one at all
The Territory by Bradley Denton - an interesting alternate history
The Best and the Rest of James Joyce by Ian McDonald - I mostly skimmed this one, didn't like it at all
Naming the Flowers by Kate Wilhelm - a sweet story
Outnumbering the Dead by Frederik Pohl - this was a great novella! What would it be like to be mortal among a society of immortal?
