So generally, I'd agree with you. But the thing is, this is so much more interesting than another 30 articles and links to tweets about Edward Snowden's current ___location that I'm perfectly happy to upvote it.

And then something more from the HN discussion, in which jlgreco and agf posted interesting anecdotal about the topic.
