It's refreshing when you find these interesting websites and articles, and it's also encouraging to know you're part of the solution when you build them.
1. Self publish, I.e. Host the blog yourself. There are many options but I personally go with Hugo/Netlify which uses git and markdown as my "backend" and has the upside of basically being free.
2. Use a publishing service such as Medium or Substack. This is easier, but you have less control over your content that you would self publishing.
Irrespective of this, getting people to read anything you write is the hardest part. You need to share your content, talk to people etc, it takes time.
I sometimes mention them on IRC and other stuff (and I have my own NNTP server), but would want to have some better way too. I would hope that others (who are interested in these kind of things) can join too, in order to help with this projects too, and to learn about them, possibly someone else can make something (and/or learning) too.
I also mentioned them before on Hacker News too, but had hardly gotten any response from that.
I do tend to post there. I have been doing this while I procrastinate to start my own blog (self hosted).
Have you posted them here? My recommendation is to not post both at once. Wait a week or something between them. Also, add a comment explaining you are the author and you are going to answer questions (assuming you will).
I have a page like this for my book: https://www.indiehackers.com/product/deployment-from-scratch
Is this a trick question?
