The most important realization about FOSDEM is really:

There's no way you can fully experience it or do it optimal.

It's really about making sure you get value out of it, listen to some interesting talks and meet some people.

It is been years since from my last time, however already about 10 years ago, it used to be either stick to a room, or stay close to a door and leave 10 minutes earlier, to try to get a spot in another talk, equally staying close to the door.

It's about collecting stickers.

It‘s about getting a selfie with the blue PostgreSQL elephant wandering around campus. :-)

It's about the friends you make when collecting stickers.

Sounds a lot like McMurdo

It's about meeting people who go to FOSDEM.

I was sitting behind you as you wrote this comment.

I just wanted to tell you that.
