Did it get taken down already? I think open-sourcing the algo would materially change the value of the deal.

Twitters main value is its user base (especially including most journalists, "stars", politicans, companies,...) I would say the algo itself is worthless, but my estimate would be nowhere near even 1B$.

Any worth that "the algorithm" has is not in it's implementation (probably pretty standard ML prediction systems), but in the training data and weights. In isolation from the data and the rest of the code it is probably pretty useless as anything other than an example of real world ML use.

There's not an algorithm to order timelines?

There probably is not "an algorithm" on a site as large and complex as Twitter, no. There are probably dozens if not hundreds of algorithms spread throughout the codebase which affect the timeline for individual users, possibly even code entirely self-generated by ML systems.

In the end, it's still code that is being executed, which can be called "an algorithm". Algorithms are under no obligation to be simple or only include "one algorithm".

Many people have commented that it is empty. However what they do not realize is that there has never actually been an algorithm and that is why it is empty.

If there is a total set of data, and a subset of it is produced for users, there is an algorithm. `SELECT TOP` is an algorithm. A ML model with a trillion parameters is an algorithm.

There is no "no algorithm."

This is most likely the correct answer. I doubt there is a single piece of code or algorithm that controls all of twitter. From my limited perspective it's just a catch phrase to simplify what is likely tens of thousands of lines of code.
