How do comment @replies work?


  1. I view a post. (Say this one for example)
  2. I see a comment below by kiamlaluno -- What is the topic, exactly?
  3. I believe I know the answer. I start composing my response.
  4. But waffles was faster and responds first.
  5. Without refreshing, I respond to kiamlaluno without explicitly naming @kia: I think I know what this question is about...
  6. Now I see:

    • What is the topic, exactly? -- kiamlaluno
    • Um narwahls, what else? -- waffles
    • It's about comment notification? < me >


  • Did my comment notify waffles? Or kiamlaluno <-- like I intended?

  • If it does notify waffles instead, could this be changed or should I always explicitly name the user I'm responding to?

This edited question isn't quite what i mean (will keep it though as it's related)

I know that if i comment after a single person comments on a post they get notified. What i'm asking is if i load the page before that comment has been made, will it still notify them (even though from my perspective there is no comment)?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

What is the topic, exactly? – kiamlaluno Aug 25 '11 at 16:43

I'm rather certain that it won't notify waffles. My guess is that also kiamlaluno won't get a notification. Best would be to just test this. I'll write an answer - can you please post a comment, @M.Tibbits? Then I'll start composing a comment. – Hendrik Vogt Aug 25 '11 at 17:13
It didn't notify me because two different users commented before your comment. If I were the only one to comment, then your comment should have notified me, even if you didn't use "@kia"; at least that is what I have understood. – kiamlaluno Aug 25 '11 at 17:49

OK, you are asking what happens when you write a comment that is directed to the first user who commented, when there are no other users who commented, you didn't use a @-reference (because you were referring to the only user who commented the post), but when you add your comment, there is somebody else who wrote a comment before you.

In that case, neither the users (the first and the second user) get notified. The automatic notification happens between two users who comments on a post, when there aren't other users who comment. In this case, the automatic notification would have worked if the comments followed this order, for example.

  • kiamlaluno
  • George Duckett
  • kiamlaluno
  • George Duckett

To say the truth, the automatic notification for George Duckett always work because he is the author of the question.

Accepting this as it answers my exact question. i.e. the check for who to send is server-side, so the fact that i'm looking at a post with only one comment when i'm posting mine is meaningless. – George Duckett Nov 16 '11 at 13:22

This is just a test. Please don't comment (yet), unless you're M. Tibbits.

EDIT: Now another comment, please.

And here the outcome:

The intended @kia won't be notified in this case, and @waffles won't be notified either. Note M. Tibbits' screenshot:

Silly silly Comments.

Sure thing. Sorry 'bout that. – M. Tibbits Aug 25 '11 at 17:15
Sure I can ..... – genesis Aug 25 '11 at 17:25
OK, I've started composing. I don't think M. Tibbits will get a notification if I submit this after another comment is posted here. – Hendrik Vogt Aug 25 '11 at 17:25
So, @M.Tibbits, did you get a notification of my previous comment? (For posteriority: The above comments of M. Tibbits and genesis-φ are both answers to now deleted comments.) – Hendrik Vogt Aug 25 '11 at 17:27
@Hendrik, Nope I didn't. I wasn't on the page. genesis, were you notified (by Hendrik's comment?) – M. Tibbits Aug 25 '11 at 17:27
I'm still pretty certain that @genesis wasn't notified of that comment "OK, ...". – Hendrik Vogt Aug 25 '11 at 17:30
Time to catch an airplane. I'll be back around in a few hours. Thanks for the test @Hendrik! – M. Tibbits Aug 25 '11 at 17:30
@Hendrik No I was notified just about "I'm still pretty..." where you mentioned me – genesis Aug 25 '11 at 17:33
