Quality of product - Not quality of coding.

Yes, both impact each other, and if facebook was just shoddily coupled together it probably wouldn't be a great product, but so many engineers get into this mindset of needing finely tuned clean code vs a working product.

When people were switching, how many decided to use facebook because the coding style of the backend was really clean and had good isomorphism?

There's a balance with this, but so much of it's success was being at the right place at the right time, and if you spend a massive amunt of time not building product and just building good code, you're going to hit a failure.
