You're not the only one. I don't donate to Strange Horizons for completely different reasons (it feels bizarre to donate to a market that I hope will then pay me--I've sold poetry and, years ago, reviews there, although not any stories), but the half-a-story thing here annoys me. Especially since there's $4,000 between the two goalposts and even if they make $9k I am kind of doubting the $13k. (I could be wrong; I haven't really tracked their funding drives in the past, so I don't know how much they tend to make.)
