&gt; What about Maker Faire, HOPE, DEF CON, etc.<p>OK, as someone who&#x27;s been to all of these.<p>The team&#x2F;cooperation part I think he&#x27;s referring to is that CCC will have a large area dedicated different hackerspaces&#x2F;assemblies. So c-base gets a corner that they decorate, as does Metalab, while many smaller hackerspaces will have a ~12-seat table dedicated to their group, where they can put up any cool projects they want to show off.<p>Maker Faire has something similar, where local groups will get an area to show off. HOPE has had some more topic-based assemblies like TOOOL. DEFCON has workshop tracks and more thematic &quot;events&quot; that happen, like DEFCON Shoot or the bike ride, but not as much of groups of real-life co-conspirators making things happen, with the notable exception of 303.
