Ask HN: Why Companies Do Not Provide RSS Feeds of Job Openings

It seems like a no brainer for them and yet very few companies actually provide one. I have found only two which do so: Canonical and Oxide.

Imagine applicants subscribing to RSS feeds of companies they are interested in. No more job boards or sifting through 100s of listing to find the one. I can configure my RSS reader to filter out jobs I'm not interested in. I can set up alerts for jobs requiring specific skills. The possibilities are endless.
