In the year of our lord 2023, people are still launching immature products with "we built a clone of a tiny subset of Twitter" as their use case? Come on. Twitter is huge because they have to support a huge number of use cases. Using this proprietary framework won't magically make complex use cases go away.
As we mentioned in the article, Instagram just spent ~25 person-years building Threads which is a barebones clone of Twitter. Not only did we build our instance 30x faster than that, we have way more features like federation, hashtag follows, polls, DMs, global timelines, and more. And Instagram didn't start from scratch as Instagram/Meta already had infrastructure powering similar products.
