Mostly a problem that a person who will find a "Revelation" will place it into one of mentioned three sections (or will place it in "meditations", as people usually do).
A person who search a Revelation will never find it anyways.

Adding another section will add confusion, IMHO.

addition:
I think that really should be done in this direction -- is better clarification of what and where people should post, so that posts could be sorted better.
Sometimes people post ordinary questions in "Meditation" section just because they exist longer on a first page of section and hence has more chances to be answered.
