While not about AI or the algorithm mentioned, on the subject of little errors that you can't convince anyone are errors.... In 2011, I wanted to copy the reddit ranking algorithm in a project of my own, so I went to source code to look at it... the algorithm in the source code I found wasn't doing anything at all sensible with negative-sum voted posts. I thought I discovered the error, some terms swapped in the simple equation, the sign for positive/negative was misapplied. I blogged it, and [posted it to reddit](https://www.reddit.com/r/programming/comments/td4tz/reddits_...), only to have MANY people, including reddit employees, tell me I am definitely definitely wrong, and the algorithm was working as intended. And that I was in fact not the first to notice what I thought I noticed, and point it out, and be told by everyone I was wr

ong. OK, I didn't really understand what was going on, I couldn't make sense of the algorithm if it wasn't wrong, but so be it. I updated my blog post to say that people smarter than me said there was no error in the reddit algorithm, all I can say is this variation makes more sense to me. Then, three years later in 2014, a commit was made to the reddit source code with exactly the correction I (and others before me) had suggested all along. The one that everyone piled on to tell me how dare I have the temerity to suggest reddit source code is wrong. https://github.com/reddit-archive/reddit/commit/50d35de04b92... ¯\_(ツ)_/¯ Open source means there are lots of eyes that can find bugs, but sometimes they can't convince anyone they've found a bug. (And of course, then reddit close-sourced their code in 2017). I never did end up using the ranking feature in my own project, that I had wanted to copy from reddit. I didn't end adding "vote" features to the app.

I've posted this a few times, but there's a snapshot of reddit from 2017 that you can self host: https://github.com/reddit-archive/reddit Why not just do that? Sure, it's a lot of python, and probably full of security holes, but there are enough reddit users to fix that, and the risk that your reddit instance might be taken over by malicious people is lower than the risk that centralized reddit will (since it already has been...) Anyway, each time I link to it, I get crickets in response. Not sure why.
