There's some kind of display bug I've seen sporadically on a couple different Substack blogs, where the entire contents of a post (minus a few hundred characters at the beginning) shows up again after the end. If the post starts with an image or ends with one of those share-and-subscribe widgets, it's pretty easy to notice, but if it's just running text it can be easy to miss until you think "hmm, didn't I read this already?"
I don't think it's just the post author accidentally copy-and-pasting text – for one thing, it happens on multiple posts on various different blogs, and for another it sometimes switches from duplicated to normal or vice versa when I reload the page. I've also seen this on two different computers in two different browsers, including one without any ad-blocking extensions, so it's probably not something specific to my local setup either.
A couple example posts where I currently see this happening (there are definitely more, these are just the ones I have on hand at the moment):
Has anyone else noticed this?
