The most exciting thing was the emergence of what I think might be the first killer applications written in Erlang. I might be wrong, but my gut feeling is that what Alexander Reinefeld showed us will be the first killer application in Erlang.

Only a few language nerds are interested in programming languages in their own right. Most people are more interested in what you can do with a programming language than with the underlying language. Thus is was with Ruby. Ruby on rails was the application that drew developers into Ruby. It made them want to learn Ruby so that they could easily build web applications.

Alexander Reinefeld told us about an Erlang implementation of the Wikipedia that not only has a stunningly beautiful architecture, but which outperforms the existing Wikipedia.

Applied to Wikipedia, Scalaris serves 2,500 transactions per second with just 16 CPUs, which is better than the public Wikipedia.
