It's the wrong conclusion. For example, yesterday there were two submissions of "Linux 3.9 introduced a new way of writing socket servers"

https://news.ycombinator.com/item?id=6269332 (222 points)

https://news.ycombinator.com/item?id=6270330 (dead, 3 points, 5 hours later)

The second one was submitted by a user with more karma, average, and days in HN.

Sometimes a story is submitted by two persons and the dupe detector fails. One of them get traction, the selection is by random events, like the hour of the submission, how many upvotes it get's in the first hours, which other stories are in the first page, ... I have seen some good stories that get only 2 or 3 points, and after a month someone else submits a similar story from another source and it gets 50 points. It's also a matter of luck.

Was the second article posted with the '/2' at the end of the link? Things like that seem to cause most filter hiccups, I tried to discount those obviously.

For science and all that, can you think of other examples?

edit: Oh I see it is different chapters, /1 /2 etc. Nevermind that.
