  That's not the move they made; they moved to Scala. Their original Rails app couldn't scale. They now use Rails on the front end, but the real data isn't Rails.

    The newer link doesn't mention them using Rails anymore. It's probably still in use in some internal apps, but the main twitter.com site should be 100% Scala now.
