It's been going on for as long as I can remember on HN. Anecdotally I've noticed peaks around the time one article is submitted then you get a rash of me-too submissions. After that things quieten down, on the front page, for a few months. Some are interesting because they can be articles on, at the time of positing an idea, an obscure theory where current world events make the article more relevant. Everyone's mileage may vary of course.
