Threads not showing up in New Posts

I start few threads, but have noticed that when I do, my started threads unlike other members, quickly disappear from the New Posts listings if no one has replied within a brief period. Today as an experiment, began a thread in the Earth Science & Environment sub-forum that I purposely expected few or none might comment on, at least quickly.

On most web boards, if one is logged in, whether one's own thread or someone else's, if you are the last person posting on that thread, it won't list under New Posts until someone else posts. The advantage of that algorithm is that it is a sign one doesn't need to waste time opening up the thread to see if someone has since posted. But if one then logs out of the board and then later anonymously views the New Posts listing, it will show up. So the algorithm must Set a variable when logged in that inhibits New Posts listing such but that variable then should become Unset as soon as one logs out. On other web boards, that is a way to actually see all New Posts.

Today after posting the above thread, indeed it did show up on the New Posts listings when I looked some minutes later. I noted the exact time so I could look for it later. But after logging out then waiting a couple hours then anonymously without logging in and looking at the New Posts listing it had disappeared just like in the past.

Looking at the listing showed other threads but not mine during that period. To verify that is an abnormal behavior, I noted there were other threads with zero responses both for today, yesterday, and weeks ago. Thus it appears whether I log out or not the variable indicating I am logged in or not, stays in the Set condition. If new threads don't show in the New Post listings, it is a sure way for others to remain unaware of the thread as it soon disappears out of sight, out of mind into back pages, never to be commented on.

You may know this, but if you click on your user name at top right, click n Your content. You can also hit whats new on the left.
Indeed that always works even though the thread wasn't showing on New Posts.

Your "vast emptiness" thread is on page 3 of the new posts. Time marches on
Like magic, it now suspiciously shows up for this person too on Page 3, as though my inquiry herein resulted in some action changing the algorithm state. @Buckeye, did you also open up the thread without posting? (Such might have Unset the variable?)
 
I didn't post in your thread. I suspect it was just driven down to page 3 because of the sheer number of more active threads.

I carefully double checked the first 5 pages and per my original thread time/date that was approximately 9:40am 9/8/2023 that indeed should have been on Page 3 between 2 other listed threads. As noted, I noticed the same thing in the past, so purposely performed this thread as a test. In a few days, I may quietly do so again. Not anything of importance but as someone that spent a hi tech career debugging, such processes tends to catch my curious notice.
 
"New Posts" only lists threads you haven't read, it's not about when it's updated. This is the basic rule.

When you are the last poster of a thread, you must have read it, so it won't be listed in "New Posts" regardless of whether you have logged in again or not.

If you visit as a guest, don't expect it to work accurately, the system can't remember what a guest has done on this forum, and it doesn't make sense to do that.

Sometimes a thread you've read may appear in "New Posts" for a short while because of caching, but it should be display as read status (not bold font).

Contrastingly, 'What's New' lists recently updated threads irrespective of your reading status.
