I could use a more robust platform or a vps host which claims better uptime, or even find a cheaper tld for my domaim, but this works fine for me.
The rest is optional, with good free choices up and down the stack - we're blessed with almost infinite options, paid and free.
It's not easy to have your own little corner online - but it's not hard either. And it doesn't have to cost.
For discovery I really love Bubbles (https://bubbles.town) & they even have RSS feeds.
The only thing I'd say anyone needs for blogging specifically is a domain name, but that's more to do with the nature of blogging where the author "owns" the space where the writing lives. When it comes to that there are enough free services that can provide you with the space and subdomain.
There's a weird phenomenon I've been noticing in the last two years-ish where a lot of people have become obsessed with blogging and sharing their thoughts online in their own personal digital space. I've even seen old personal blogs gain a surge of activity in the last year whereas in the years prior there would be at most a post per year.
Also regarding the point about text editors I've never understood why people use dedicated markdown editors? I thought the whole point of Markdown was minimal formatting that's hassle-free to write in whichever text box you happen to find yourself in making dedicated software kinda redundant, no? As opposed to something like Org where you rely on org-mode in Emacs otherwise GOOD LUCK when editing it "by hand".
I apologize if this comes off as a rant, I've actually enjoyed this particular post!
