This strategy may work in the short term but I can't imagine how it will be sustainable. As engineers continue to flock to the hot new thing, they will be leaving a pile of bugs in their wake. The article mentions that developers are responsible for fixing their own bugs but that just won't scale. Once a developer has been there for two or three years, their body of work will have grown so large that they will no longer have the capacity to perform maintenance whilst working on new features. Your example of bugs in fan pages is a problem that will only get worse.

Perhaps they just need to sustain this model long enough to get to an IPO.
