The only thing bothering me about that thread is the person/persons who like to reignite the conversations of why we should all like/hate Fauci, why masks are smart/stupid, why COVID is/isn't serious, why Trump is/isn't a maniac, etc.
Otherwise, I think it's best to have as few locations as possible for the conversation. One thing I like to try and avoid is having people create multiples of the same thread (like what happens in places like Reddit all the time) just to share the same opinion(s) being discussed in an already active thread. We lock that one and we'll probably see a lot of similar threads pop up.
These types of threads also have a tendency to die on their own. Or, in the case of the SF Megathread, it'll get to the point where there really isn't anything new to discuss and it's time to move on to fresher things. At the moment, all of this is still very fresh.
