If you actually wanted a job, why not just read through them all and contact the ones that are near and interesting? - it's really not that hard, I read them all and I'm not even looking for a job.
HN could instead do with a proper job board. I'd suggest that a job board should not be restricted to advertising just specific jobs like every other board does. In a small startup roles will not be that well defined yet. You should be able to post just a company and say they are looking for good people, by stating:
- What the Company does / the problem it solves
- Capital raised and current situation
- Technologies currently used
- Location
