Honestly? I think the challenges are really just the vehicle to hang the interactions from. In many ways, it doesn't matter what they are, because a lot of the appeal about them is in getting people to talk to each other about all sorts of crap (y'know, like Baymax's superiority in the event of a zombie apocalypse :D)

I also think this year has been a tough one for people on that. There's a lot of extra burdens and challenges on a lot of folks at the moment that make those interactions more difficult to maintain, especially at any sort of deep/meaningful level. So, basically, what I'm saying is: a curse on this decade of the two thousand and twenties, which has simultanously lasted 13 months and 300 years!
