Michael, just wanted to note that I have been eating up your Wonder Cabinet site with a spoon. Really fun stuff there.
As for the story, I was left with mixed feelings. It ticks a lot of the boxes that one might expect from a story coming from somebody who would manage a site like the Wonder Cabinet, including found footage, unexplained events and creepy dread, all of which can be good things. But while the writing was obviously miles above the typical creepy pasta, the theme does still feel overly familiar, and the lack of definition or explanation for anything left me less mystified in a good way, and instead sometimes confused during the reading and unsatisfied at the end. The character glitches on tape, as well as in real life, and... Well? And? Oh, it's a mystery. About.. glitches. OK then. But it felt anti-climactic to me. There could have been anything odd about "Ana", but instead she just.. flickers a bit. Yes, it gets worse, which is to say it gets better, later on. But I suspect many of us saw the viral aspect and haunting reappearances of Ana thing coming, in some form or another.
I think the effort from Gemma Files and Stephen Barringer about five years ago did this suicide on tape that involves a viral plague thing better in their story on the subject - Each Thing I show you is a Piece of My Death. Some may like the added mystery in Ana Log without the longer history behind the tape that the Files story had, but I felt like that one added up better than this one.
This was an enjoyable story too though, and I feel guilty being critical of it when I had such fun listening to it. I liked how Ana continues to deform in her later iterations, leaving her burdened observers ultimately surrounded by misshapen horrors. I felt like I could have used more of Ana's perspective to better feel the horror of her predicament, but then that might have taken away from the sense of mystery around her, I suppose.
