I know the trend from the LiminalSpace subreddit. It's nice to scroll through, peaceful yet slightly unsettling. But I think a lot of that effect comes less from the physical "in-between-ness" of the spaces and more from the fact that they are places you would expect to have people, but which don't. The article notes this but only in passing. You never see a photo of a busy corridor, for example. They are always empty which is what gives them that uncanny feeling. I went over to that subreddit now and there are even a couple of photos of people's homes, which are surely the opposite of liminal spaces. But they appear not only empty but also anachronistic (with, eg, 70s decor or older wallpaper) which also seems to be a trend with this aesthetic.
