I&#x27;ve actually done the next stage: researched a problem, found a really helpful Stackoverflow answer, which it turns out I had written, which was a reply to a question which it turned out I had also written.<p>The only disappointing thing being that due to causality constraints, I was unable to upvote past me&#x27;s answer <i>or</i> further past me&#x27;s question, which was a shame as they were both really useful.
