That is great. We should post in all of them if possible.
I think that Steven could show object centric debugging, someone (anne maybe? ) present moose. and for minimalistic experimental emerging languages carolina could propose candle and the bootstrap processes.
I think that Steven and Carolina talks are mature enough after all the trials, and a moose talk could be really cool. Maybe Julien's SQL or Benoit's translations should be really good for catching potential students and specially some investment capital for the team :).
Sadly me i don't have much to show :(.
But if we have the stand i plan to be there.
