> not sure why it is such a mystery feature from people on this site What would be substantive would be to teach us that this can be done, rather than point out (based on dubious evidence, AFAICT) that we don't know yet as a means of one-upmanship. I don't believe you're trying to be mean, but I suspect that a vast majority of people would feel otherwise which is worth avoiding if you're able. BTW, lack of "reply" option is probably due to the delay feature (the duration varies based on certain criteria) and can be bypassed by clicking the timestamp, which loads the comment in its own page, on which there is no such delay.
