Each of the forums exists for a specific reason, Essorant, and I think most of those reasons have been detailed in other threads. For example, the Holiday forum harkens back to a time when the more senior Members could directly submit poetry to the main site right from within the forums, and indeed, many did. I wanted to encourage more holiday poetry on the main site, so I opened the Holiday forum and programmed it so that anyone (not just senior Members) could submit. While that reason is no longer valid, the poetry posted there when I needed it guarantees the forum's continued existence.
Many of the other forums exist not as a reservoir for a particular genre, but rather as a relief valve for Open Poetry. For example, we don't have a Dark forum so those interested in it can more easily find it. We have a Dark forum so that those NOT interested in it can more easily avoid it. If we had a really big run on haiku and a lot of people complained about it, it's quite possible I'd segregate it, too. I don't expect that to happen, though.
Generally speaking, and in spite of a lot of necessary exceptions, I don't believe in segregation, not of races, not of gender, and certainly not of poetry. We learn best, I think, through wide exposure.
Or, as my mother used to tell me, "How do you know you don't like it if you won't taste it?"
