Nokia selected by NASA to build first ever cellular network on the Moon

I don't browse the site by the front page, but by '/newest' and regularly see the same story reposted within minutes of being posted by someone else. And, while the 'up vote lottery' may explain why one particular posting of a story gains most popularity, it doesn't address the question of why no-one bothers to check before posting.

Take the Nokia/Moon story I specifically referenced. Multiple people were still submitting that one the day after it first broke.

Did none of those people have the gumption to consider that, on a site, like HN, obsessed with all things technological, such a technology fan's wet dream of a story might just conceivably have already been submitted by someone else, during the preceding 24 hours?
