For folks that want to engage / learn more, there's been an annual miniKanren workshop and also a monthly miniKanren hangout online. Interested folk should totally come to either both!

Is there more information somewhere?
We do have a monthly call of miniKanren/OCanren researchers from around the world, where someone presents on their research. If you are interested, please send me an email!
