I haven't noticed this....but it would be interesting to know if the broadcasts are waking people up.
If you know the broadcasts woke you up why not tell us on this thread.
In my imagined scenario, I'm not sure if it's broadcasts waking people up. I think it could be that some are awake, but stuck in, afraid...but they're lurking. Then they see a ridiculous broadcast like this week's, and they say, "Fk it, I'm joining up."
