I've long wondered how much HN karma I could farm by keeping track of the top-X HN blogs and auto-posting the links with a bot.

There are also a number of other blogs I read that are semi-regularly on HN and aren't on the list that I expected to be. Maybe just didn't quite make the top 100, and I'm over-indexing on my personal preferences. eg. Matt Levine's Money Stuff crops up semi-often, and Bret Devereaux of ACOUP gets most of his posts on HN.
