Multiple people have reported that Astral Codex Ten posts load slowly, and this has been my experience as well, especially on a mobile device. I often find it difficult to read a post because of how slowly it loads. According to an "official explanation" from Scott Alexander posted in the Reddit thread, this is because all comments are loaded when the post is loaded, but commenters contend (rightly, in my opinion) that Substack is at fault for loading comments so inefficiently.
This question resolves to YES if I notice that reading Astral Codex Ten posts is less annoying than it is now, on a consistent basis, before 00:00 UTC on January 1, 2025. Otherwise, this question resolves to NO.
I will use my personal mobile device, reading as I normally would, to test this. The reduction in annoyance must be noticeable, but not necessary total. I don't read ACX too often, so it may take several weeks to determine that the reduction is consistent. The reduction may be due to Substack improving how it loads comments, Scott Alexander collapsing comments by default, or some other means, but it must apply to the default logged-out view on a mobile Web browser.
I may provide liquidity subsidies but will not otherwise trade in this question.
There is an unofficial mirror site called ACX Reader that has the tagline "Because Substack is too damn slow".
You might already know this, but it's much smoother when using the official app.
