I know there's one user who maintains a site that lists all of the job postings (forgot the url), but personally I'm not a huge fan of the layout.
Try it out for this month.
This is likely in part due to the HN audience composition, but my hunch is that its also partly because people are making assumptions about the HN audience composition.
I'd love to see one post for technical hiring and one post for business hiring. I think calling it out as its own post would actually encourage people to post those other jobs that they might normally think are not appropriate for the HN audience.
I have a suggestion, please make it fortnightly .
I second pknerd's suggestion to make them fortnightly.
Search/Sorting is a definite room for improvement so I can narrow down the opportunities that I'm interested in by location, skills, etc. Obviously, the HN comment system is quite limited for that stuff.
