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.
