The number of times I heard this joke: Oh, nobody goes to FOSDEM anymore, it's way too crowded. But it's true. They have a serious overcrowding problem, with the queue outside longer than the number of seats, while the room is already packed.

The app had nice indicators of where the overcrowding was, though. It pushed me to less popular talks, where I discovered some hidden gems. I also came home with a big list of recordings to check out.
