For me, I don't think I'd be blogging frequently enough or with enough of a common theme to warrant setting up my own site. Instead, something like Medium springs to mind as an option - although I'm aware they've had some bad press recently.
So bloggers of HN, where do you put your blogs?
Whatever you do, though, please don't use Medium!
Wordpress is great too, though isn't as plug-and-play as you might expect.
I would avoid the temptation to build & host your own site, as your goal is to _blog_, not code.
Also, consider capturing email addresses and sending all of your new posts to your subscribers.
It's very motivating to see a small, but growing list of people who want you send them everything you write.
Here's the simple design I use if you want to replicate it: https://stewfortier.com/subscribe (it gets about a 30% conversion rate)
Happy writing!
If personal, any self-hosted platform will work (WordPress, blogger.com, or Webflow).
If business, you can post articles on your site. Some well-known marketers only post once a month. But they do a ton of promotion + optimize to rank in search. From what I've observed, it's not necessary to keep a consistent posting schedule, but it helps in other ways like building up the habit. More in-depth content tends to increase search traffic. That's why you'll see bigger brands like Shopify write a ton of articles daily.
The advantage of using another platform is it gives you the possibility you'll get some of their traffic if you understand their system.
In my opinion, don't worry about your platform. Use something that works. The bigger issue is how to get your blog found. And whatever platforms you use, your URL structure should be maintained so that links don't rot and readers can still find you. I made the mistake of going from blogger.com to self-hosted WordPress. I should have just started with WordPress.
