In the blog post (A Recipe to Promote your Site) over on on the Stack Exchange blog last August, it was made very clear that communities should make every effort at promotion. I am not aware of any real promotion efforts that have gone on in the past or are in the works at present.
I think our biggest problem is that at least for the moment, our primary userbase is users of Stack Exchange, rather than students, teachers, and translators (など) of Japanese. We need to get our name out to the Japanese community, rather than just the community of Stack Exchange.
So I ask: What can we do to promote JLU?
