(2007-07-06) Twitter Scala Message Bus

Another approach to improving Twitter Scalability involves using a Scala-based Message Bus instead of a Data Base for lots of interactions.

Active Messaging [supports](http://code.google.com/p/activemessaging/wiki/Active Messaging) Message Passing for Ruby On Rails.

Chitt Er uses Erlang to attack the Twitter challenge.

I think Twitter may become the test case for Scalability of architectures, a different kind of Hello World.
