Is there a reason every recent post on this guy's blog has been posted on HN?
Further, there are other people who's every bog post makes front page here. It's how we roll. Stick around for a couple months, and you'll see it. There are also cycles and waves of people, topics, etc.
Many HNers follow his blog (which tends to be of consistently high quality) and/or twitter stream.
