At first glance it seems OpenHack provides the organizer with the concept, branding, and inclusion on their site... anything I'm missing? what are the next steps?
Perhaps another interesting question is "Is there anything which differentiates this from a local HackerSpace?". If the goal is to not focus on specific languages or environments, then why not go one step further, and not focus specifically on software?
I understand that there is need to draw the line somewhere, so I don't have any problem with them focusing on just software, however another HN article could be:
