Last Saturday I attended to this important event at Universidad de Palermo where I was speaker together with other 6 southies : (MatiasW, Mr. Salias, Ejadib, BetoO, JohnnyH and DiegoP). I am not sure about how many people attended to the event, but I can say that all the session I went were full.
All the speakers were asked to record their sessions, so I think Microsoft will publish them in the next weeks.
Meanwhile, If you want to know about what I spoke, the slide deck I used for the in my presentation is available to download here.
