People around the world save money.. Students in Leuven might not be doing that.. but they sure save internet.
KotNet is a service.. or a project, or aaam... whatever, through which every student has access to the internet in their rooms. I'm not really sure if that is sponsored by the university or the price is just included in our rents. In any case you have a monthly limit on your download.
One never thinks about it, but every picture you open,.. every video you play on youtube,.. every word you write/say in skype.. is download. Without realizing this, students turn into upright savers that search for places to use someone's wireless.. Questions like: "How much do you have left?", and answers like: "Mine is not green anymore, it's yellow..", are a normal part of conversations..
