I think I see where you're coming from. I was recently thinking of starting up a technical blog as a form of self-promotion and to have something to show to potential employers. But I also wanted to do something that I felt was good and worthwhile to readers. So I thought about the sorts of programming blogs I'd read in the past that I could maybe emulate or use as a standard. And then it occurred to me that, for the most part, they're either a waste of time, not terribly interesting, or even harmful. I've had better luck with reading textbooks, though maybe I just prefer to try and learn a subject in some depth. But when what you're really selling is your knowledge and expertise, I can see why people do it.

I think if you have the right motivation it's fine. To be blunt I don't think self promotion and hirability is the right one heh I think that will lead to low quality content.

I'm not really a blogger, but I have written and posted stuff I found hard or interesting, like documentation for my self. I reffer to it occasionally too. Idk if any readers got anything out of it. People seemed to like it. I did find that worthwhile though.

If you want to do better, don't shy away from showing times you were wrong.

It's hard to present a universally right answer in tech (or in general), it's not hard to know when you chose wrong answer, and going over it can teach others how to identify the right one and show that you're capable of growth
