I definitely noticed that as well. It could be a self-propagating cycle? Maybe people see an article from The Atlantic, then while they're there they find another article and post that? The more people post articles from The Atlantic, the more people who go and read other articles there and go on to post them here. And personally, I think it is a pretty good publication. They have some interesting stories and they are generally well written.
Well, the submitter of this article has a 5 year old account. They frequently submit news articles from a variety of sources, and are also an active commenter. (Though, they do seem to like posting quotes.)
The other two atlantic articles on the front page are from 2-3 year old accounts that likewise post a lot of pieces from various newspapers.
You're welcome to dig through their posting history for a conspiracy, but it's not jumping out at me.
Doesn't have to be new accounts. "Pay to post" is a regular occurrence and a lucrative side business for people on high-traffic, user-curated content sites like Reddit and Digg.
Hmm, you know, my comment defending the Atlantic posters actually does have a weird amount of upvotes. (Not a joke -- it's at +37 right now, which seems high given its placement and late timing in the thread.)
Seems suspect. Not sure why this type of content is being posted on hacker news. It's a poorly written article not having to do with this site's prerogative..
There are three on the frontpage right now, with 2 more in the next three pages (all of which frontpaged at least for a moment).
