The Reiser filesystem will continue to be used by those who understand its value, despite its bad reputation within a small niche of people[0].

On a more on-topic point: my experience has led me to believe that the Reiser fs (Reiser4) has a narrow use case only when quick operations (seek/read/write) on an inordinate amount (hundreds of thousands+) of small (<1MB) files is required -- and that high performance is absolutely necesaary.

I failed to find any other use in my experiences with it.

I was quite surprised when I initially ran out of inodes my first go-around, as well.

[0] Really, no one cares that much. Whenever the name comes up in less formal circles, obligatroy low-effort "dead wife" jokes surface, but what usually follows is discussion on the filesystem's merits. The outrage is from a vocal minority that I would deduce aren't in any position where choice of filesystem is of their concern.
