Hugo Awards 2008 - short story winner & nominees: Brief summaries & my rankings

Denvention 3 has posted 2008 Hugo Nomination List. List below ranked according to my preference. List will get appropriate decorations as their process progresses.
Update 10 August 2008: Winner has been announced.

Hugo award process defines short story as something less than 7.5 thousand words in length, with a margin of 20%.

Nominated stories (5 stories, best first).

Quick observation: this appears to be a far better list than this year's Nebula Awards short story list.

1. [winner] Elizabeth Bear's "Tideline" (A); download text or MP3; Asimov's, June 2007; science fiction: A sentimental robot teaches life skills to an urchin. Already in my best of the year 2007 list.
2. Mike Resnick's "Distant Replay" (A); download text or MP3; Asimov's, April/May 2007; fantasy: An old man in love with his long dead wife's younger self!
3. Stephen Baxter's "Last Contact" (B); download; George Mann (Ed)'s "The Solaris Book of New Science Fiction" (2007); science fiction: A description of apocalypse.
4. Ken MacLeod's "Who's Afraid of Wolf 359?" (B); download text or MP3; Gardner Dozois and Jonathan Strahan (Eds)' "The New Space Opera", HarperCollins/Eos; space opera: A man on the run becomes a king maker.
   
5. Michael Swanwick's "A Small Room in Koboldtown" (C); download text or MP3; Asimov's April/May 2007; fantasy: Senseless murder mystery. Has magical creatures but familiar political & ghetto characters, & utterly arbitrary plot.
