I love how much attention spaced repetition gets on HN. Does anyone know if there are any communities for researchers or engineers working on spaces repetition and adjacent problems? /r/spacedRepetition is basicly dead. I really wish there was a place where I could discuss space repetition research with technical peers. if such a place does not yet exist and there is interest in creating one, please reach out I am easy to find. Maybe we could start a Discord server.
