Many times I intend to post something, even plan it out in my mind. Sometimes I make a draft in my editor first. Still, I get distracted and forget to post my comment from time to time. Until now I've been able to tell if I really commented, or merely planned to, by reviewing the question from my favorites tab, and either finding my comment, or seeing that it's not there and knowing I still have to take the final step and actually post it.
An answer here is one I am almost certain that I commented on, and I think I even got a response to it. The reverse logic around the OP's use of a quote from R. Stallman is what sticks in my mind. Admittedly my ancient, code addled brain has some bad sectors in it, yet I'm sure the comment was posted.
The only thing I can think of is that my comment was deleted, along with the response to it, by someone with that power. (A mod, maybe high-rep user, not sure, and it don't matter.) I think I recall a much larger list of comments than is currently there as well. Anyway, since I can't see any remnants of my comment in my profile page, on the question page, or in my inbox, can someone tell me if I really did post the comment, and it later got deleted?
I don't care if it was deleted as part of the site's upkeep. That's a legitimate process for the good of the site. I just want to know if my mind is developing more bad sectors, or not.
