Comedy aside, it depends on what you're trying to do.
To be clear, if you want reviewers, you have to take into consideration the reader because that's pretty much logic for you. As in, why wouldn't you take into consideration the reader if you're also trying to get people to like and review your work?
However, if you just want to tell a story and have fun with it, then by all means, write what you want to write. Occasionally, what you want to write might cross over into the kind of territory where you get readers, but don't be too surprised if you don't get a huge amount of feedback. This is because chances are, what you want to write and the kinds of genres and subgenres that attract readers aren't exactly the same thing, and if they aren't, you'd have to earn a readerbase the hard way if, one day, you decide you want one.
(Of course, as a disclaimer, I'd just like to say that if you plan on publicly posting your stories, keep in mind that by default, you're considering your readers in one way or another. This general rule is why you bother to proofread, post at sane speeds, avoid blowing off canon completely, and uphold the other given rules. Otherwise, you could theoretically say that you wanted to write a crapfic to have fun or because it's your style if you go by the "write whatever you want" logic without defining it. When it comes to content, though, the above two rules of thumb apply.)
In short, if you want craploads of reviews, yes. If you just want to have a little fun, no, except when it comes to following the basic rules.
