It depends on your goal, and how you define your target readers.
I assume your goal would be to post an article you wrote here and achieve some level of engagement (as you noted dev.to is blocked).
So, if you are planning to post on HN, the problem I assume you are trying to solve is finding an online url that carries some credibility in order to not turn off potential engagement.
Looking at https://hntrending.com/ and clicking “domains”, filtering to last week, I was surprised to see that 90% of the domains were well-known (GitHub, twitter, WhatsApp.com). Scrolling to less popular domains, we start to see some substack links and then I saw “interestingengineering.com”
Maybe I’m just a sucker for a good domain, but I would probably click a link to Christine.website or Christine.IO instead of christine.blogger.com.
Also, if a link isn’t to Bloomberg.com or nasa.gov, I’m going to assume the article is from someone’s personal, less journalistic-oriented position. So, an interesting domain like buildruntest.site or improving.code adds to my perception that I may hear an interesting perspective that isn’t covered in the news.
I recently switched companies, and having an interesting domain with some content on it was helpful to show employers. When I was hired at Apple, my manager noted he had glanced at my twitter feed and seemed to believe I was clued into the space I was hired for.
I assume you aren’t seeking monetization. The amount of work and advertising required to reach traffic needed for that level can be pretty massive (differing by topic, of course).
A lot has been said about writing as a way to self-reflect and also improve internal thought. So, if your goal is self-reflection or practicing the craft of writing, the “where” doesn’t matter as much.
One last thing: I was surprised at getting SOME engagement on a youtube video I posted about a server issue I figured out (HP DL360). I rarely ever post on youtube and haven’t blogged frequently in years…but I regularly get 100+ views each month. So, with all the talk about algorithms rarely helping small-fry content creators…perhaps my anecdote can encourage you that someone, somewhere may find value from what you post.
