Discussion article for the meetup : First meetup in Stockholm
To clarify, the time is 17:00 Swedish time.
I'm going to sit at a table for at least an hour and see how many people show up. There are meetups happening all around, so it ought to happen in Stockholm too.
When you enter the library, turn right. You'll find some tables -- mine has a big sheet of paper saying "LessWrong meet-up". Look for a guy with long hair.
The library is wondrous, and open until 21:30, so you could take the opportunity to explore after you meet us.
