Oh absolutely, I want to make it clear I didn't intend to insinuate on any particular person, more a trend I've seen on HN over the years.
I've seen it a few times before when $wellKnownProgrammer has an article hit the top of HN, then their next several blog posts all seem to hit the front page before everyone fatigues of it. I'm guessing certain people and sites become "flavors of the month" for both submitters and upvoters, but maybe HN has the stats to figure it out.
Are you sure you're not the one that's experiencing the Baader-Meinhof phenomenon? I subscribe to Anandtech's RSS feeds and they had a slower period recently for technical articles.
That doesn't invalidate your theory, but I don't think it applies to this particular submission.
