(And one of them appeared to oops while juggling a sockpuppet account on HN to help promote -- which was a little suspicious because that tactic seemed incongruent with the goal they claimed. I suppose, with that project, the non-US intel value could've been intentional. It's much easier to imagine a lot of people being motivated to follow Area 51, just out of curiosity and the mystique, and not seeing any harm in it.)
Which prompts the thought: with all sorts of geopolitical tensions going on right now -- as much as we Internet-age techies can be global citizens who extend fellowship (through HN, open source, research communities, companies, etc.) -- maybe we should try to be aware when actions we are considering doing would stray into delicate global balances that we don't understand. We don't know enough to know everything to avoid, but maybe sometimes we can guess, so it seems worth the occasional thought.
