@Vinayak Yes, it's experimentally confirmed. As with editors, you do not get autocomplete but ping works.

Seems either I misunderstood the paragraph on spaces, either something is broken, because I frequently have a problem with spaces. See here in the comments for example, I tried to notify @Joachim Pileborg, and no link appears in the comment (same here). How do I know if he got notified ?
Is there any way to escape an @ ? I might mention a java annotation in a comment and the comment processor tells me I can't send to more than one person.
@StevenVascellaro: The "@ pointer" is not updated when users change their username. I now this because on Web Applications and Stack Overflow there is a user that frequently participates in the tags that I follow and they have changed their name a lot. (I usually use they instead of he/she when I don't know the proper pronoun ).
(1) This says that a backtick (`) can allow a second “at” symbol in a comment. Apparently this works even if the backtick isn’t matched (i.e., if the ‘@’ symbol isn’t formatted as code). But does this mean that `@ is never treated as a ping, even if it’s the first ‘@’ in the comment? (2) This lists abc@name as an “example” of a non-ping, without giving a general rule that it is an example of. Is ‘@’ always treated as a non-special, literal text character if it’s preceded by a non-blank? (There’s a comment (above) about \@, but I don’t understand it.) … (Cont’d)
(Cont’d) … (3) This lists *@name* as an “example” of a non-ping. What about *I hope @name sees this.*? (4) This lists [@name](URL) as an “example” of a non-ping, but I suspect that [blah blah @name blah blah](URL) works. (5) I understand that the algorithms for detection of fraud and spam, etc., are secret to make it harder to game them. But why can’t we get official documentation on how ‘@’ works?
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
complete the sentence: my question is about...
use tags that describe things or concepts that are essential, not incidental to your question
