QCon short recap

So, what do we make of all the information that was poured over us the last days? What is the most important? Of course, we will need to investigate all this stuff further. But at first outlook, I would say:

1. REST looks like an important new trend.
2. Erlang might answer the need for more Concurrent Oriented programming languages.
3. Java for enterprise applications is very much alive, also for real time systems.

Additional:
DSL's keeping turning up at conferences like these, but I don't really see what's the big deal. But maybe I'm missing some point.
Architecture is maturing, but there's no silver bullet.
Agile is maturing nicely, thank you.
Ruby on Rails fits nicely in their niche.
Domain Driven Development is a new term but nothing really new.
