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

>>gianca+1x
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.

>>MBCook+wI
I don't think so. Seriously think about it. How many active users does AirBnB have? How many put their home up for rent, and how many rent in a year? I reckon you get more tweets in a day than AirBnB rentals in a year. That's how big Twitter is or small AirBnB is. :D

Twitter was bigger but they don’t run on Rails anymore where I gather AirBNB does.
