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.
