I love when friends do this. It's hard to keep up with people and what they're up to. Publishing and letting people subscribe to me is a great way to share things. A few examples of some friends who are doing this:
Justin Searls (fairly known in Ruby and Rails community) mostly quit a lot of various social channels though publishes on some of them one direction. He started a podcast that wasn't meant to be guests of some specific topic, it's just him updating you on things. What he's working on, what he's learning, random stories, etc. - https://justin.searls.co/casts/
Brandur who I've worked with at a couple of places (Heroku previously, and now Crunchy Data) who writes great technical pieces that often end up here also has more of a personal newsletter. While there are technical pieces in there at times he'll also talk about personal experiences my favorite one is some of the unique experiences hiking the Pacific Trail (https://brandur.org/nanoglyphs/039-trails).
This gives me heart. I like writing about technical things, but I also like writing about personal things, concerts I went to, whatever. I'm a whole person, and I never liked the pressure (mostly from social media) to build your "brand" around one genre or style of writing. For me, my site is a personal one where I post about things I'm interested in. Ham radio, machine learning, my travels, pay phones, whatever. Maybe less useful for a reader or audience building but...I just like to write and share things.
