Sadly it's really hard to get a promo fixing bugs or optimizing code.
Ship it quick, ramp up some high profile users that don't actually care much about what you're offering, and jump to the next project before anyone notices the problems.
Works every time.
There are 10,000s of SWEs at Facebook and this project was at most a handful of SWEs. (As stupid as it is, it did not significantly detract from prod bugs.)
