The main reason to do this would be to make things more organized. When I or Xel start making light novel or VN threads, it would be much easier to navigate if they all belong in a separate section instead of having to search for threads one by one.
The reason I don't make title specific light novel or VN threads is because they will get lost in the General Anime or Books section anyway, which would almost guarantee that no one would ever read or post in them. Having a section will solve that problem.
It may get minimal discussion or posts, but it is better than nothing. It's not like we are killing the fanart section even though it hardly gets any activity anymore.
EDIT: I also think some great discussion can be had for light novels that are currently being translated. If the posters are up to date with the latest translation, then they can discuss possible plot direction, characters, and the like without spoiler issues. Baccano, Durarara, Regios, SAO, and Heavy Object are just some of the stuff that can produce great discussion and debates.
