Really? That answer seems somewhat misleading, I don't know if intentionally. YC's biggest place to advertise is HN. In fact, look below right now -- 'Apply to YC'. In addition to reminders of when the applications are due showing up in frontpage, etc.
That answer is not misleading IMHO. Apart from their own website such as this, they don't market through other venues such as radio, tv etc.. Never heard of YC until I was doing research through the web and found hacker news.
And HN, sort of.
Ten years later, people now see YC as "we can give you a better future/make you rich/famous/etc if you work hard and receive our magic touch."
It's a very word-of-mouth spreading meme. "This company makes you rich, be one of us, shub shub."
Is it really fair to call content on their own website marketing? I suppose there is a sense of the term in which that's true, but given the context I'm not sure that I would say so in the context of objecting to their claim.
