I apologize if this has come up before on meta, because it almost certainly has, but I couldn't find it.
I frequently come across recently asked unanswered questions that I find interesting. However, I haven't been able to find a satisfactory way to watch such questions for answers. The best I've come up with is adding it to my favorites or simply leaving a tab open in my browser and refreshing it periodically.
This is in contrast to when I ask questions. I am immediately informed of answers or comments.
Is there way to set a notification to trigger when a question is answered? Does anyone have better techniques for monitoring interesting questions?
