Honestly I'm not sure what those are, but poetry in itself is difficult, free verse is the easiest type/style, speaking from personal experience.
Reason 1: There are more free verse poetry than other types/styles, therefore it has higher chances of getting picked. Reason 2: Any limitations(like "rules" for how it's written) in poetry makes it increasingly more difficult to write at all, so writing good...?
DDs are just a feature, a feature that the community can help control by sending in suggestions. There are four lit CVs you can note with your suggestions (full details including individual suggestion guidelines can be found here: [link]).
Fixed form is difficult because the piece not only has to have interesting content, and good strong writing but also needs to fit into the rules of that form effectively and that the form doesn't dominate the readability. Often you can find with fixed form poems that a lot of pieces feel forced by the format because the writer is focused on that over the content. Getting the right balance is usually where the DD worthy pieces are- but its all about finding them. I believe there are pieces out there, but we need help from you guys to help us find them
Just to echo what's already been said, it's probably due to several factors. 1) The kind of work that tends to get posted; 2) the kind of work that tends to get suggested for DDs; and 3) the work among that pile the gallery directors think is worth featuring. If you want it to change, then you're going to have to suggest poetry or engage in some kind of effort to draw attention to formal poetry on dA. You'd hardly be the first person to make this effort.
I would also not disregard the fact that formal poetry is simply not the current dominant mode in Western literature.
What drove me crazy, for the two and a half years I posted DD's, was the fact that the people who bitched longest and loudest about what I featured were people who NEVER recommended anything to me. If you want to see different DD's, get off your ass, find some work you like, and RECOMMEND them.
You rarely see any poems with exact rhyme schemes and meters here. By exact I mean something like ABBA ABBA CDCD ABBA or what ever where the rhythm/meter/number of syllables is exactly the same for each "A", for each "B" and so on. And where the poet doesn't rhyme "pizza" with "freezer" (just as an example).
Anyway, why do you care? Be glad that there are *any* DD's given to literature deviations.
Each person experiences DeviantArt differently. Some people use it as a way to increase their customer base, some for tips on improving their form of art, and some as a social network. I, personally, use it as storage and as entertainment. I've lost documents before when computers crashed, so now I post my photos or writings online. And, as for as entertainment, most of my time on this site is spent scrolling through deviations and reading stories, poems, or comics. As I have a bias towards fixed form poetry and humor, I happened to notice that it was less frequently featured in Daily Deviations. As that's the quickest and easiest place to find quality work each day, I was expressing my desire to see more of what I liked.
Also, notice how I did not blaim or criticize in my post. I was asking a two-fold question. What reason people might think there could be for the lack of (what I perceived to be) diversity and what were some examples they knew of for previously featured fixed form or humor poems in Daily Deviations (so I could read them!).
For future reference, please don't make multiple threads on the same topic.
As people have already mentioned, it's a matter of what is out there as well as what is sent to us directly. Not to mention that, since fixed form has strict guidelines, if a work doesn't meet them it's out, whereas if it had been in Free Verse it might have still been featured.
