My guess is that after ~15 years or so, Twitter is probably either At Scale already or never will be.

Ship anything? The site works now. How much NRE is required just to keep relaying tweets and showing ads? My guess: not much.

My comment is more about where it is headed. If you have been following Twitter you can read accounts of engineers pulling all-nighters, working over the weekend and “launching” the verification feature. Then, read accounts of users trying to use it but said feature not working. A few iterations of this for different features/products, and it will quickly impact his ability to ship anything (likely due to no automated testing in place, poor design decisions, etc.).

Here is an example from a customer:
