The author's point is that for some projects wireframing may not be appropriate. I've had this experience on numerous occasions where let's say a full-color design comp or an interactive prototype would better serve the concept, which may be hard to grasp otherwise.
This is especially true when taking a design first approach, or when your project gains nothing by illustrating hierarchies, navigation, or other wireframe-able things.
The author either thinks the readers are either stupid and don't know the difference between a Hammer and a Screwdriver and why you can't drive nails with a screwdriver....
Or the author is stupid and was driving nails with a screwdriver and wrote this post to explain why they changed.
Look, it's great when the person in charge of deciding policies is the same person doing the work, and the same in charge of selling it to whoever must be convinced. But most people work on different environments (yep, even when they own the company), and communicating, even things that appear obvious to one of the parties, is crucial to make right decisions on those other environments.
For example, if you are looking into hiring a designer, if you didn't read the article and makes the obvious decision of asking a wireframe from the biders, you just alienated everybody that could make your site great. That this is obvious for the alienated designers changes absolutely nothing.
This is a very low-class and frankly foolish way to interact with someone criticizing your work. Even if it's true that drakaal is not a popular content-producer, and even considering he could have phrased his points more respectfully, that's no reason to just blow off his reasoning entirely.
Anyway, here we all are caring and talking about something he wrote.
I think you will find from my comments on HN, My youtube channel, and my interactions in volunteerism, with political movements, and law enforcement that I may be a Troll. But I'm not gutless.
