This page in a nutshell: Just because a topic is not interesting to most people does not mean Wikipedia should not have an article about it. Also, when writing articles about obscure topics, Wikipedians do not have to think about the general audience. |
An obscure topic is a topic that is only interesting to a small number of people, like people that are studying the topics that the subject is involved in, teachers, or fans. Obscure topics are perfectly okay to have articles on Wikipedia, as long as they meet notability guidelines.
