I live close to Malmö, which hackspaces are you referring to? I only know of two!
So that makes Kontrapunkt, Bageriet at Volframsgatan, Fabriken at Stapelbäddsparken and this 4th near Värnhem.
Of course, I believe there aren't enough nerds for 4 hackspaces but it's still pretty cool. :)
We do currently cooperate with the Filurum (https://www.facebook.com/filurum) gifted children group to provide a meeting place every week - in fact, it's what I'm doing later today.
