I think the notification only works on Q&A section, but still does not work in blog section.  It did not work when they first introduced the feature and they were aware that day and said that they were going to work on it.  I have not heard any updates so just assumed it hasn't been fixed yet.

I think it only works 50/50. It used to work better before the upgrade happened.

I hover 'Mr Mouse' over the grey flag left of my photo on the upper screen & a drop down menu tells me pretty much of the time. 80%

I don't think notifications are sent for sub comments.

I usually just check back for subcomments....

Fred, I do not believe that feature works on comments on posts.

I often check back on posts for sub comments because I don't seem to be getting notified... or they get lost in the notification roll.  I believe many sub comments are missed.

Not sure. I have not really paid attention.

There are many breakdowns still but overall it is working effectively since the clock is back in sync.

Great question. Confess not having a clue!

I have been notified in the past...

I don't believe notifications are received for sub-comments but I could be wrong as difficult as I may believe that to be.  

I'm pretty sure it shows up in my notifications that someone commented on my comment.

I only get notice of comments, not sub-comments.

If it shows I will look if not on to the next.

Fred,

It is still an issue.n I does not work on posts like it does on Q& A

Good question. I was just thinking about this the other day. No one seems to have an answer. 

I used to not tag if I'm replying to their comment.  I believe I still see notifications when someone replies to my comment and I know I see it when they reply to an answer of mine.  Now I tag everytime, just to be safe.

I thought these tags worked but I have never checked. I guess I have been an uninformed user.

I do not get notified of "sub-tags"

Unknown.  Safer to leave a new comment....

No idea.

I don't think you get notice of a "sub-comment" if you don't tag the person you are commenting to.

great comments

I'm not sure about the answer, but I like a red arrow touch:) 

Fred Griffin - I do not think this is fixed, yet.

Nope, never worked.

I seldom get a notification,,,I think it is shut off

I am notifed via the tag.

I believe Debbie Gartner has the correct answer.

These days, some things that have worked for a long time no longer work.

I think we still get notice of the tag.

Fred Griffin I don't believe they do. Since we are allowed to leave sub-comments it should.
