The Cathedral, the Megachurch, and the Bazaar

If you’re of a certain age, you probably remember the essay The Cathedral and the Bazaar. The TL;DR was that old open source was the cathedral of exclusive developers and groups. Then the Bazaar showed up (which was the Linux Kernel for example) and that freed us from the shackles of the cathedral. Except if we look at how things evolved, it wasn’t actually a bazaar. It was a bunch of roadside churches that are now megachurches. But there is still a bazaar, and it’s holding up our modern infrastructure.

It was a bad essay at the time and I don't think you can make a good essay by trying to build off it. Adding "megachurch" to the already strained metaphor didn't improve it.

As you point out in your linked comment, the original essay captured the zeitgeist of the time. It also influenced and inspired many people. From that perspective, it's hard for me to agree that it was bad. However, I don't think the content was original at the time (perhaps that's what you mean by bad?) - in the sense that ESR wasn't out ahead of people blazing some new trail and it also didn't hold up very well factually.
It was certainly influential. It's just bad on its own merits.

(1) That rule refers to things people have posted to HN in things like "Show HNs" (or their moral equivalents). It isn't a general prohibition on critique, which would be silly.

(2) You may have missed the link to ~1,000 words of detailed criticism of CATB, on which I support my claim here that CATB is bad.

There’s nothing I’m seeing in the text as it is written that suggests this to be the case. There are just a lot of comments I see that amount to: “I don’t like this,” which can be an interesting signal by itself but not if users refuse to elaborate on it, which is what I (erroneously) thought was happening here.

I did miss it, sorry. I clicked through and didn’t notice that the top comment was yours. I assumed you were just linking to a past discussion.

I’m sure you already know this, but on the off chance you don’t, you can click on a comment’s timestamp to get a permalink to the specific comment, like this:

HN is a common law system; the real guidelines are the guidelines page itself, and the "jurisprudence" of years and years of Dan (and Tom) writing moderator comments. But you also know you're a little off the rails when you've derived a rule that would prohibit, say, criticism of a book --- "Teach Yourself C In 24 Hours is a bad book". Of course that's OK!

But yeah, the big thing here is that the substance of my critique is on a different thread. It's disfavored to retype things you can just link to. I'd be irritated with me too if I just said "CATB is bad!" and left it at that.
