Since Strange Horizons publishes far less than 10% of all science fiction, that seems fine.

Pure originality is exceptionally rare, but that's not really a bad thing. More and more I believe that the human experience is primarily defined by rhymes and analogy, trying to avoid reusing prior work is futile.

"What has been is what will be, and what has been done is what will be done; and there is nothing new under the sun" (Ecclesiastes 1:9, RSV2CE).

I think you are right, but also, that it is totally legitimate for Strange Horizons to say "we really really want only original work." So long as they don't also say "only original work is valid to create", which is where I (and maybe they, given the disclaimers) take issue with this list.

I wonder if some stories work well with the peer group of authors/editors, but not so much with audeiences.

For example, it's annoying to me as a reader when stories are straight-up rewrites of say the odyssey or hakespeare, or put greek/roman gods in our universe. (same with computer games that are hex based and show the hexes, or card-based games that show the cards)

I also think you could cover 90% of these just by watching Star Trek.
