Should I build a "personal brand"?

I have been tossing and turning on the idea for basically years. Swaying back and forth, with varying levels of commitment, on building a "personal brand" for all of my content online.

Here is my dilemma: I like to create content online. Writing useful articles, teaching with video recordings, and generally sharing as I build in public. But I find that I really swap back and forth over what "brand" I publish that content under.

Right now, I am posting my developer specific articles to one website. Which is different from the old YouTube channel that I used to publish videos and articles under (which started in 2009 and has over 11k subscribers).
A good portion of the content overlaps, being mostly developer tutorials, but some does not. The YouTube channel has some general tech or YouTube specific tutorials on it too.

But I also have my personal website. Where I like to share the "build in public" style content as well as the more personal inner monologue content (like this article here). But I also have some assorted technical/tutorial style articles as well.

Do you have any thoughts? I would love to hear them :)
