I'm really confused about what is the author intent with this article. At first read, it is pointless. The first paragraph pretty much resumes it: "These are my rules, but they're not good because I break them more often than I adhere to them". If this is intended as a starting point for a discussion, as the author claims, I think a forum is more appropriate format, and at least start from some previous existing convention discussion. This just looks like trying to reinvent the wheel from scratch.
Blogs tend to be the way a lot of advice, guidelines etc are disseminated in the software world, so that's the main reason. I don't know of any major forums in the Clojure world, for example, that everyone is aware of and contributing knowledge to. It seems to blogs, irc, the mailing list, stackoverflow.
This is on Stuart Sierra's personal blog, so it's just him sort of thinking out loud. He's got a lot of that on his blog, and a lot of it is really valuable. I refer to it often when I want to get some new ideas on different ways to do things in Clojure.
