twitter/the-algorithm
I've worked on very large scale recommendation systems at a FAANG. If Twitter's system resembles anything like ours, the concept of publishing or open sourcing "the algorithm" doesn't make sense.Even if we were to open source all associated code and publish all related documents it would be very difficult to make sense of the entire system. That is precisely why companies such as Twitter A/B test the hell out of everything. What most people think of as "the algorithm" is a complex system that receives many inputs (maybe hundreds) and has dependencies on many other internal Twitter services. Tweets likely pass through multiple filtering steps as well as scoring before you ever see them. Each of these steps is highly contextual, depending on: location, past tweets, verification status, etc. You can attempt to predict the effect of a certain change, but you never know the actual outcome until you test it.I think what will ultimately happen is that _some_ details will be published. Elon will parade that around as a victory for free speech as Twitter is now more "open". In reality, nothing of value will be gained as "the algorithm" isn't a simple function.
