I've just took a spin around the 20m band and it's reasonably lively, maybe a bit more so than usual, but the band isn't packed. Besides, I think most ham enthusiasts were already spending most of their time at home (retirees) talking about illnesses (diabetes, usually) :)

Edit: Stopping on 14.340 I got a Hawaii/California net and was able to hear people from Hawaii pretty well, which given my crappy antenna is a bit of a feat. I think propagation is improving a bit at last, which will be nice for people stuck at home.
