@blunders: The underlying reason is probably that this is not part of the academic field of linguistics. And why is that? Because linguistics is about the way language works as a natural phenomenon, as perceived externally. So a constructed language is more about how an individual person would like to design an artistic project. That said, questions like
why did Esperanto become more popular in x than in y? might be on topic, though perhaps they would be a better fit for History.SE. Questions about "how do I find x" are only on topic if they ask for resources about linguistics. —
