Substack isn't invisible to Google. Not sure why you'd assume that.
WordPress is fine but if you want to primarily focus on content, try Ghost.org. I think their editor and design options are superior to WordPress.
On one hand, the simplicity of something like Substack is tempting. I just want to focus on writing.
But if I go that route, every post will be invisible to Google, trapped inside their ecosystem. I'll be renting my audience on someone else's land.
The alternative is a WordPress blog, but wrestling with plugins and updates on top of writing every week feels overwhelming.
For those of you who have been down this road:
1. If you were starting over today, what would you do? 2. Is the discoverability problem on closed platforms as bad as I'm imagining, or am I overthinking it?
