I'm not trying to say erlang is much more efficient in the 
general case than Java, as I've heard it isn't, but that they 
chose a language and OS that was highly optimized for their use, 
concurrency, and were able to scale using fewer servers as a 
result, as opposed to just throwing general-purpose java/.net and 
more servers at the problem.  Just another example of right tool 
for the job.
