“It’s tough to make predictions, especially about the future.” (multiple sources ) And if you organize a large conference for the first time, you have to do a lot of tough predictions. How many people will attend? Who are the interested speakers? What is your community going to organize? A lot of questions whose answers sometimes depend on or influence each other. For example, if a lot of people attend, speakers get interested in talking. Or if the community organises interesting opportunities to share and learn, more people are likely to attend and so forth.
Imagine a European Union that builds its IT infrastructure on Free Software. Imagine European Member States that exchange information in Open Standards and share their software. Imagine municipalities and city councils that benefit from decentralized and collaborative software under free licenses. Imagine no European is any longer forced to use non-Free Software.
