I appreciate the tip, but I'm having the exact opposite problem. I have that box checked and I want notifs when people reply to comments that aren't mine (on my memes), but I'm not getting them. (I do get notifs when people reply to comments that aren't mine on everyone else's memes.)
I can see why people in the ms_memer stream wouldn't want that, but I would find it helpful because I suck and nobody likes me, but I still want to see what they're saying. 😋
