[Pharo-project] What do you want in a talk?

...about "Objects, Open Source Software and Startups" ? the thing is I was invited to give a talk in Latinoware 2012: http://2012.latinoware.org/en/ and I'm still preparing the talk so I'd love to hear suggestions on what you think people might found interesting about objects and open source and startups. The plan is to talk a little about economics innovation and startups done in Pharo and Amber, which is my main experience at flowing but I'd very much like to hear what you guys have as additional suggestions/experiences So, I'm all ears :) what did you found so interesting in your experience working with objects? sebastian o/
