Do YC companies get preference on the homepage?

I'm guessing the answer is yes, but I see a lot of posts about jobs at YC companies that don't seem like they're getting enough attention to be on the homepage. I'm assuming they artificially put them there to help them, but that feels like ads/spam since this is generally used as a forum.

If that is the case then admins probably can't do much about it, but it'd be good to keep that in the `jobs` tab or something so it's not cluttering up the news page
