@pockets I tend to lean into doing CWs rather than not if there's any question about it because the "cost" associated with using them is extremely low; if you want to see it, you click one extra time. So as long as you're interested, you can see what's going on.
As far as what content merits that, I try to treat it as maybe a slightly more intimate setting than just being in public with strangers...say, the same as a cocktail party. So, if I wouldn't bring it up at a standard I-don't-necessarily-know-all-these-people cocktail party, but I want to discuss it here, then I use a CW.
