> Another kind of job ad is reserved for YC-funded startups. These appear on the front page, but are not stories: they have no vote arrows, points, or comments. They begin part-way down and fall steadily. Only one is on the front page at a time. The rest are listed at jobs.
The mods disabled the comments in that kind of post because each time a business post a job position, it would get essentially the same comments. But when a YC company post a new product or other big events (or someone else post a complain against a YC company) then the discussion is enable, because it's expected to get a different discussion each time.
