I often use HN as an archive, so I end up in very old threads when I search for particular things. As a result I quite often have tabs open with threads that are years old. And more than once I tried commenting/upvoting, thinking it was a recent thread. I don't think you're wrong, but I do agree that it's easy to only remember the good bits. Anecdotally at least apparently old threads can be just as bad, and that's even after search for specific topics!
