I put my heavy blog content on BunnyCDN. It’s impossibly cheap. I’m happy to pay a few quarters if a blog post happens to blow up.

Hey, I really like the animated diagrams in your posts. Could you share a few tips about how you create them?

Thanks! I use Inkscape to create the SVGs and then animate them with javascript and greensock. I still haven't quite found the right layer of abstraction for this, so it is a tedious process that takes a lot of time. Once I do, I might release a tool that will help with it.

Ahh so it was an informed choice. I understand. But Hacker News doesn't do previews anyway :)

Would a `<details>` block also work?

I'm not sure. Wouldn't the webcrawler still have to load it?
