It was fun but indeed, I spent a lot of time waiting in line for talks and in some rooms I couldn't even enter at all.

For talks which will obviously be popular, go to the talk before it even if it's not as interesting. It's not common to have two super-popular talks in a row in the same room.

That is how it's supposed to be. You can watch the talks at home at any time but the opportunity to meet random yet like-minded people from all over Europe is unique.

On my side, I had the feeling that there was less room/talk full to the point you can't enter compared to previous years.

Except in the H building.

Not the same experience of course, but I think you can watch the presentations you've missed https://fosdem.org/2026/schedule/streaming/
