Liminal Space

So, how does a rather normal Roman concept get turned into whatever liminality is now? The answer is that the idea was picked up first by Early Modern philosophers (I think Kant was first but he had a very unmystical definition of the liminal -- but I won't bore you with... Kant). Keep in mind that during this period the limit in mathematics was being developed.
It gradually regains something of its spiritual, Roman-like meaning as the 19th century progresses and also finds an appropriate home in anthropology to describe places and ideas like the Roman ones and in (Jungian I'm guessing) psychoanalysis where it's used metaphorically as turning point or a threshold between sanity and madness.
After that, the French philosophers (maybe from existentialism on -- existential literature, Satre and Beckett come to mind, have some sublime depictions of liminality) of the later 1900s, ran further with the psycho-metaphorical version. Besides its already-established connection with madness, it came to be, I guess, a sort of goal. I think the aim was to push the writer, reader, and message into a liminal space where cultural and other boundaries could be crossed with the hope of seeing things from an alternative perspective.
From there it trickled down to colleges and culture at large (again). Sorry for the ramble. I hope I got my facts correct.
The cycle usually goes like this:
1. I see a genuinely haunting image or piece of art on the Internet and think "Wow, this reminds me of that 'liminal space' stuff I read about."
2. Now that it's rekindled my interest, I search for 'liminal space' and find a mixture of half-ass creepypasta and very bland images of abandoned buildings.
3. After a short time of searching, I get bored and forget about liminal spaces for a few months until it comes back to me.
I don't know if this is just an example of the Pareto principle (80% of 'liminal' art is crap) or if the label 'liminal' is just so frequently misapplied that it's become useless.
For anyone in New York, there’s a pretty good art exhibit in Brooklyn about liminality called the Museum of Future Experience. (The museum might do other exhibits, but it’s been liminality for as long as I’ve known it).
