All your submissions are autokilled. I think that's because you only submit from a single source, (and you appear to be the only person submitting from that source) and you only have a single comment, but you'd have to email mods to find the real reason. hn@ycombinator.com

I think it's a shame that your submissions are being killed because this one, while short, seems interesting. (Actually, they're all really short. A few people complain about long-form articles not getting to the point, so they may like this site.)
