It's really comical not being able to fit into a devroom for a talk and noticing that people inside weren't actually paying attention but rather just holding a chair for another talk coming later...

Thankfully the hallway is then full of people interested in that subject!

Yeah :(; and streaming might have made it worse since you can now just stay in the same track all day and follow other talk.

You could try to force people to leave after each talk in popular tracks but it would probably take too much time and you would have people leaving early to go back to the queue ...
