Is this the future of science fiction anthologies? It's certainly a future. I'll be fascinated to see if kickstarted books remain viable into the foreseeable future, or if they're a bit of a fad. One thing is clear, though. You need to know what you're doing.
Editor Bryan Thomas Schmidt seems to know what he's doing. He's assembling Speculations K. C., an anthology of science fiction stories both new and reprint (spoiler: mine will be a reprint -- but a good one!) by science fiction writers either associated with Kansas City or with next year's Worldcon, MidAmeriCon II. Where (ahem) I'll be a guest of honor.
Personally, I think it would be a great book to bring to MAC II for autographs. Particularly if you snagged more than your friends did. Not that I'm suggesting you make a cutthroat game of it.
You can find the Kickstarter campaign, decide whether you want to support it, snag yourself an early copy here.
