I expected to disagree with this post but actually found it really worthwhile.
For my own blog [0] I usually start writing because I feel I just learned and did something cool which gets me excited to share it. I also write only about topics I'm very familiar with (graphics and performance). Very safe. And still I learn a lot by forcing myself to really examine what I write about and always leave with much better insight into something I thought I knew inside and out. And still I'm always very nervous that people will dismiss it or find huge faults in it. I've found a few issues myself after the fact, but commenters have been nice.
Maybe I should risk pushing myself into unfamiliar territory? On one side, I absolutely loathe blogs written in an expert voice by someone who is clearly a novice - and I don't want to be that person. On the other hand, people who know me often encourage me to get more technical and detailed in my posts because they recognize that my blog is very simplified (meant to be approachable) compared to what I actually do day to day. My upcoming post will definitely lean into the more low level and technical. Hopefully that will be appreciated, but I find myself really nervous about it.
One of the best ways to clarify your thoughts about a subject is to write about it, and one of the best ways to prove to yourself that you understand it is to be able to write about it clearly. Indeed, my primary motivation to write is to order my thoughts and better understand the universe I live in.
It is surprisingly difficult work, but so is lifting weights. That is precisely why I insist on doing it myself. If I let an AI write for me, it would be the same as letting a robot lift weights for me. Yeah, it would be easier, but I would not get stronger, nor would I gain the confidence and self discipline that comes from doing hard things.
I think a better way to understand is talk and discuss it rather than just write about it. AI can be useful for this, like instead of it lifting for you, it is holding the punching bag instead in your metaphor.
Yes, writing clearly makes you understand your thoughts etc. But it is one of the methods and we shouldn't extraploate how much a person understands things based on whether they write or not.
Arguments and discussions are still superior form of learning to me than just purely writing and thinking.
You raise an interesting point. I agree that discussing a subject with a knowledgeable mentor, AI or otherwise, is a great way to learn. But I think back-and-forth discussions are limited as a means of testing your mastery of a subject. Especially with complex and nuanced subjects, being able to organize them in your mind is an essential part of mastery. You will not know if you have mastered them unless you can generate a clear and coherent description of them entirely on your own. With a mentor prompting you, step by step, you are relying in part on the mentor’s understanding of the subject to guide your thinking.
It is like the difference between multiple-choice and essay exams. In the former, the questions you are asked reveal much about the structure of the subject to be explored and of the relative importance of its facets and the many nuances within. In the latter, you are on your own: you must conceive of a coherent map, render its form onto a blank sheet, and populate it with what is important, with everything being sensibly connected.
I also write a lot about things I learn and not always fully understand yet. My secret worry is that one of my readers will meet me in person and quiz me verbally on the subjects of one of my articles. I would end up sounding really dumb compared to the impression made by the article!
When it comes to pretending to know something about things you don't understand, I think there's a big difference between talking and writing. Talking is bad because you're not equipped to form intelligent off-the-cuff sentences about the thing. But writing can be okay, if done with care.
Some things I would be able to talk about because I have insense opinions enough to remember (e.g. insurance purchasing decision logic), or they are easy to remember (the alpha-max plus beta-min algorithm), or I wrote about them recently enough to remember (how to perform an FFT). But ask me about anything else (sloppy confidence intervals for Pearson correlations?) and I'd just stand there.

What’s wrong with posting about something interesting about the world you have discovered without arguing any point? The author seems to argue that polemics are the only valid form of writing. Even for a polemicist that seems a bit self aggrandizing.
Seeing the title, I expected this to be a blog post trying to convince me what to blog about, written by a person who does not yet understand if his perspective is correct.
Please, no. Don't blog about things you don't understand yet. We have far too many people and LLMs doing that. After you really understand it, then consider blogging.
> Please, no. Don't blog about things you don't understand yet.
Do you really mean this? Or do you mean "When you blog, be honest. Don't pretend to understand things you don't."?
Blogging about things you are learning about, especially if you invite feedback, is a great way to learn and to build a shared understanding within a larger community.
But I agree 100% on the fake-it-till-you-make-it posts on blogs and LinkedIn. That stuff is a blight on the web.
I agree as long as you are very upfront about it being a learning/stream of conciousness blogpost, then it should be fine to watch how someone's learning journey progresses.
The author does outline the steps they take to make it clear
> Third, I try to make it clear on my blog who I am and what my credentials actually are. Even if it’s not explicitly described in the post, I have my real name and resume available on my /about page, so I don’t think a careful reader could be easily fooled into thinking I’m an expert on 19th-century England or space physics or LLM economics or anything like that.
If however that part is hidden and it is some confidently incorrect or pseudo guru type of post that is polluting the web with misinformation, then that is a different story.
Maintaining a high signal-to-noise ratio is important to some people, and they may completely disregard the musings of people outside their field of expertise.
I used to do exactly this, but 99% of my blog's traffic was bots, so I shut it down.
The web is on its last legs. Why bother publishing if nobody will read it? Nowadays I just write explorative/study notes in a notebook. I retain that better than typed writing anyways.
Genuine question, did you put work into distribution so people knew about it first?
I've known a bunch of people who have said 'blogging is dead' but that's often shared with a lack of sharing the work in the first place or sharing it.
The vast majority of blogs go unread, even back on the old web. I used to blog almost every day, for years, back in the early 2000s, and probably no one noticed.
But the fun was in the activity and the self-expression, both in blogging and discovering blogs. And if someone happened to come along and say hi it was a bonus. I'm trying to recapture some of that fun but it's difficult.

ADDED a concrete example: Consider this post: https://blog.moertel.com/posts/2026-07-23-on-the-nature-and-.... Do you think that posts like this are useful? Or net harmful?

Unless you think actually going through with the work of making something online is worth the effort.
