What's Going On Here, Anyway?
nobody discovers a lifelong love of science fiction through Asimov, Clarke, and Heinlein anymore, and directing newbies toward the work of those masters is a destructive thing, because the spark won't happen. You might as well advise them to seek out Cordwainer Smith or Alan E.

This is a testable hypothesis! I've rounded up a pool of younger people who have agreed to let me expose them to classic works of science fiction1 and assembled a list of older works I think still have merit. Each month my subjects will read and react to those stories; I will then post the results to this site. Hilarity will doubtless ensue!
