HN does have ads, just not a lot of them. Once or twice a day there's a recruiting ad for a YC firm inserted among the submitted stories. Doesn't have comments or upvote/flag buttons, and is just inserted between the regular stories according to some algorithm. Similar format to the way Twitter displays ads inserted among tweets that look like a tweet, except YC only makes the space available to companies in its incubator, rather than selling it.
