Agreed 100% though - amazing presentation. Just the right amount (and format) of multimedia in a way that added to the story without being overly flashy/showy.
I have seen a lot of links/comments on that story in a wide variety of different communities, including those that are less traditionally interested in internet/multimedia design than HN, so it certainly did generate some good publicity for them.
There's at least one person from the digital side of the Times that contributes to Hacker News, the person that wrote the fantastic Emphasis[1]. (I've been looking for a chance to use it.) Wonder if he'll -- forgive the ambiguity, I've forgotten his username -- show up in this thread and shed some light on our speculation.
EDIT: Ah, he's left the NYT[2].
I didn't have anything to do with Snow Fall, but I did frequently walk past the people who were working on it late at night. We don't have anything formalized like 20% time, but these projects are definitely a labor of love.
I know a couple people that are getting picked up by newsrooms for "startuppey" digital lab work, data visualization, that kind of thing. Your publication is definitely setting the pace for the field at large these days, and it's a good thing.
They can afford to put in a bit more expense in building an impressive article.
