> The number one reason people give up on blogging is because they realize no one gives a shit and they have no traffic

I heard this one idea in a software development conference a while back, that went along the lines of: "Your keypresses will be more valuable if more people benefit from them." which was essentially talking about private notes possibly being more wasteful due to less impactfulness.

That's kind of why I still write things in my personal blog (and am actually working on a blog/video series about opinionated software development) even though it's not too popular.

So that in a few weeks/months/years when something that I have previously jotted down will be relevant, I'll be able to just share a link and offer up my points without trying to recall all the minutea.

That actually extends to writing about the failure modes of software, e.g.: https://blog.kronis.dev/everything%20is%20broken/nginx-confi...

It doesn't have to be the best writing out there, or even correct 100% of the time, it just needs to serve as a historical record.
