This isn't shocking - Twitter was notorious for being held together with Scotch tape technically.

Honestly this hands-on approach is an impressive example of doing things that don't scale.

I found it amusing that Twitter was Rails' biggest advertisement. Everyone wanted to use Rails but Twitter turned into a franken app with different stacks to keep it running

Twitter was Rails' worst advertisement. They used Rails as a scapegoat to hide their bad tech. I still hear things like "Rails can't scale; remember Twitter?"

Airbnb is still on rails.. Probably the largest rails app out there for now.

Except that I'd bet Airbnb's read qps requirement is less than 1% of Twitter's. Write qps would be even smaller.

True, but on an absolute scale AirBNB is still very big.

By RPS, I imagined Shopify is largest. But then from what I understand, Shopify operate in such a way that every shop is its own app. i.e there is 100s of thousands of Basecamp / AirBnb running on the same code base and every shop is somewhat isolated.

Purely in terms of App in think the largest would be Cookpad. AirBnB never shared their numbers so I don't know.
