I have been thinking about the evolution of threads about the Coronavirus on Mumsnet.
First, we had just a few and most people hadn't really thought about it. Then we had a bunch of people asking about going on holiday, and the vast majority of people saying "Just carry on as normal". We had a phase when most of the threads were making fun of those who were concerned. Then people made fun of preppers. Then people started talking about closing schools and were laughed at. Then people started talking about panic buying and started aiming vitriol at the preppers. Then people started being angry at people who suggested closing schools, saying they were being selfish.
At this point, the threads which are moving quickly are those which are discussing new pieces of information or discussing when, rather than if, to close schools. How to provide childcare and provisions for those who need it. How to protect elderly relatives.
It's been a really rapid evolution, but I think we are getting to where we need to be.
