Hmm, I didn't think it took any of them years to rearchitect per se? Regardless, somebody has to do it =) I for one am grateful for these giants pushing our current platforms and languages to their limits. On top of that, they've gone and found solutions, all in their own ways to solve the problem of scaleability. No?

It really did take twitter many years to rearchitect and break their most problematic dependencies on Rails, yes... my understanding is that it was a 4-year process.
