I've been blogging a while now (~18 years), I find it worth it from a couple of perspectives.
1) Writing forces me to think through things clearly and when doing things like walkthoughs I often find things where my understanding wasn't quite right, so it helps there.
2) I often return to things I wrote a while back where I can't remember the details of a specific topic.
3) I appreciate when other people take the time to explain things, nothing like finding a good blog post when you're researching a topic, so this is my part of helping out.
4) Getting the odd message from someone saying they appreciate something I've written about is nice :)
5) It's helped my career. I now work in a field where I'm paid at least partly to write (security advocacy), and I've had companies approach me to talk about jobs based on them having read something I wrote.
In terms of the tech. I use, I keep it super simple. Jekyll and GitHub pages, so there's no server maintenance, just write markdown and publish.
