Cross-posting to Substack

Historically people kept up with blogs via RSS, but it's been on its way out for over a decade. These days receiving posts via email is popular, and I should probably make my posts available this way. I considered implementing my own emailing system, but bulk email is (or at least was, I'm not up to date here) a pain. Instead I decided to start cross-posting to Substack: jefftkaufman.substack.com. This will be yet another way to read my posts, similar to the LessWrong mirror and my text-only FB cross-posts.

I have a full RSS feed of all my posts, and Substack imported it fine. It doesn't look like there's an option to do ongoing RSS-based imports, but copy-paste seems to work well enough; I did this post and the previous one that way. At some point I'll look into automatic cross-posting, though right now it looks like Substack doesn't support anything good. And if I'm going to reverse engineer something I'll start with their comments implementation, since I always want to rehost comments.

One aspect that's a bit eerie is the URLs: both Substack and my blog would use /p/post-name-in-title-case as the url for a post titled "Post Name In Title Case". I've been doing this since 2013-10-28 and Substack got started in 2017 so I know I didn't copy them ;)

On AI writing in 2026

I use AI to write a little bit: I ask it for high level feedback on blog post drafts, make mechanical edits, and sometimes use it to brainstorm options for wording at a paragraph level. It’s unusual that I accept its wording or changes without modificatio…
