Considering on-topic is "anything hackers find interesting," a complaint that something is not interesting is a complaint that something isn't appropriate for the site.
I think you've seized too tightly to the word 'interesting' here. He was rejecting the advice as too paternalistic. And after reading the blog, I think that's pretty reasonable, even as I find myself agreeing somewhat with the blog.
"I'm not terribly interested in following this advice" is a lot different from "this advice is not appropriate for the site." Rejecting something doesn't mean it wasn't relevant.
Again, read closer. I did not complain that it wasn't interesting. I said I wasn't interested [in considering] such advice. The use of the same root word is only interesting (uh oh) to those in the business of equivocation fallacies.
At no point did I claim you were wrong simply -because- you used a fallacy. I had other, better, reasons for that. You are bad at this and I've become bored.
