How do you find good directories for submitting niche articles?

[Dan H]

I've been learning about all the benefits of writing quality articles and submitting to directories to improve SEO. However, I notice looking at a lot of the bigger, better known directories, that they don't have a category that fits what I would be writing about because it is such a unique topic. I'm wondering if I would be wasting my time, or how I go about finding the right directory that would want to publish the article/topic that I would be discussing. Thanks!
