Hoping that we get the second, then - or at least some interesting genre options. I find most conventional forms of poetry to take itself way too seriously or just be over-the-top ridiculous trying and failing at being funny.

Maybe there could be a way of entering one image so it's like a gallery of entries you can still diamond but not really have its own category. so people can link their art blogs and put the image in their art blogs too, but not vote on the blogs.
I'd be so down for it.

How the poll should have been done: Do you want to see a poetry contest? Yes or No.

The way the poll works now is that people who want something different but not poetry (myself and Havingfun_ISKEY for example) are forced to pick between 2 options they don't want (they don't want poetry nor do they want the usual blog contest) or just not vote at all (which is bad, cause you want these people to have the ability to voice what they want through the poll, that's the whole purpose of a poll). I'm sure this is not intentionally done this way and I doubt that if "regular" wins that we will really get a regular blog contest (like Zath already explained). But it's a typical example of a "false dilemma", which is just confusing and gives awful results.

Example:

Havingfun_ISpooKEYPoetry isn't my favorite at all, but considering that we may end up with an unoriginal theme with the regular option, I don't really know.

She stated she doesn't really enjoy poetry nor does she want to pick the regular option. In a "Poetry? Yes/No" poll she would probably vote no, which is a useful result because it correctly portrays her opinion. In this false dilemma however, she seems confused and doesn't know what to pick. She might pick "poetry" because she really doesn't want a regular contest (even though she doesn't want poetry), she might pick "regular" (even though she also doesn't want that) or maybe she doesn't vote at all (which beats the purpose of a poll). All of these 3 possible results are not useful, 2 of them falsely portray her opinion and one of them doesn't show her opinion at all.

There's just no way to vote "no", like you stated.

To be completely clear, it's important that we (the people who vote) interpret the poll options the same as the people who base their actions on the result of the poll (the judges for picking the theme/style/whatever I assume). As Zath said, if "regular" wins it will be probably be interpreted by the judges as a simple "no" for poetry even though that's not what the option said. This causes confusion and might even give rise to false poll results.
