Read the source HTML on New York Times articles, and scan the New York Times front page online from time to time to see the variety of ways that headlines can appear on the same article from the New York Times. I sometimes see a headline first as link text that leads me to the article, and then see a different headline as the article itself displays in my browswer. If I like the article and then think about submitting it here on HN, I have to think about which submission headline will be give readers an idea of what the article is about and what aspect of a hacker's intellectual curiosity the article might gratify.
To sum up, there is not always a one-to-one correspondence between articles and headlines as the New York Times is hosted on the Web.
