I noticed at lot of changes lately to HN. Such as adding flag | hide | past | web etc.<p>Also, what I find interesting was: Unlike before, I wasn't able to add in a comment to the post I have made. Trying to find out what is the cause. I have discovered something weird.<p>On MY new section, my post was showing as if it was a new post and was shown to others.
On a new browser that I wasn't logged in, my post was missing.
On my devices not connected with the same IP, my post was also missing.<p>Is there a new rule or algorithm regarding posting?<p>Can we add a section regarding changes made to HN? It can be a milestone or a documentation on how to understand or use the new features.<p>I've checked 'dang's timeline' and there are no new announcement regarding these new features being added lately. Thanks.
The "feature" you mention - having a post visible to you when logged in, but apparently not visible to others - is a long-standing feature. Posts from some sites are "dead on arrival", the mods having determined that posts from those sites are usually poor, and the better ones will be reported by other sites which are not proscribed.<p>I agree that it would be nice to have, somewhere, a complete list of features, but this is not a new one.
I think, but don't know, that URL shorteners are likely to be dead on posting.<p>Your submission below uses an URL shortener, and I think that's what's caused it to be dead.<p><a href="https://news.ycombinator.com/item?id=13210435" rel="nofollow">https://news.ycombinator.com/item?id=13210435</a>
Check the post from a new account, with "show dead" enabled in the options. Likely it was auto classified as spam. Quite a few people browse with show dead, so it's possible someone will vouch for your link and un-dead it.
