I just posted a comment beginning with @username, and my @username part of the comment was not rendered (it was the first word in the comment). Why is that so?

If you post a comment under a user named "Smith" and you're writing "@Smith", the system won't auto-complete it, because you're obviously talking to the author of that answer/question.
If you want to direct it at someone else, it doesn't render it, either. It's not a bug.
The auto-fill will activate only when:
- you're writing a comment at someone else other than the author;
- that someone else already posted a comment under that question/answer (also if these were posted by you).

The @-reference to a user is automatically removed in some cases, when that user is already notified of a comment.
For example, if Jasper Loy would have used @Alenanno, that would have been removed, because the comment was clearly for him, who is already notified.
In my comment, which is the second comment for that answer, the @-reference has not been removed because I could refer the comment to Jasper Loy, instead of Alenanno. To notice that both Alenanno and Jasper Loy should get a notification for my comment; for sure, Alenanno gets notified because I have commented the post he created.
