I think Alex confuses "scaling in the small" with performance. Rewriting Starling in Scala most probably improved Twitter but it did it make it more scalable?
To me as an outsider, it sounds more as Starling (or Kestrel) got its performance upgraded, not scalability.
May sound pedantic, but it's important to differentiate performance from scalability.
