@Do you still check on comments you left on other peoples answers even if the answerer doesn't @mention you? Yes, I always do that in the old GAG. And I continue to do so in the current GAG version because I notice sometimes they left a comment for me but forgot to @Pingju and so I didn't get a notification for that. And it also ever happened that people @ me but I didn't get the notification. It's easy for me to keep track because I have so few friends on here.
No, I just assumed they never responded until now. :/ But sometimes I go back to questions to see new opinions from other people, so maybe I'd see then if they did respond but forgot to mention me. And I agree with Jack, I think some people don't know about the mention tag.
I didn't know it was like that back then! Must have been such a hassle.
Voted C), but I am kinda torn with B). The problem is that I leave MANY opinions, so if you want to tell me something, then you should mention me, otherwise it is just sheer luck that I actually notice later.
