By the way, I try to network. In Stockholm if you see someone you know a little, it is not obvious that you talk to that person. You might, you might not. That's the Stockholm way.
These days I don't let anyone that I recognize pass me, at public transportation or on the street or anywhere without talking to that person, letting them know I'm looking for a job.
The other day I happened to meet a guy in the basement who was repairing something. You can not imagine who much interesting information I got while he was trying to make the reparation (slightly disturbed by someone chatting...). To me the basement meeting was more informative than attending a special seminar!
