Tomorrow is apparently the publication date of Beyond Singularity, a book that reprints my story The Voluntary State along with thirteen other stories by authors I would list if I knew who they were (I haven't seen a copy yet). The editors were Jack Dann and Gardner Dozois. Here's a squib from the publisher's page about the book.
Featuring stellar contributions from some of today's most masterful practitioners of speculative fiction, Beyond Singularity presents fourteen visions of a tomorrow where rapid technological and genetic breakthroughs have rendered humanity obsolete.
Available wherever books are sold, I'm sure. I'll add it to the books over to the left when I get back from my Kentucky history class, so you can click through that if you're interested. Oh, and my story doesn't technically render humanity obsolete, but why quibble?
