This is exactly the sentiment I detected in the previous thread, where a small group of people seem to have decided what the etiquette of daring to post a Show HN is. I'm not sure I remember being consulted on whether you should be keeping these gates for the rest of us. My reaction is the same as it was when people tried to argue Show HN was only for open-source software: says you.
I'm not gate keeping anything, to do that I would have to make specific statements beyond "consider other people when you post something"
Right and my point is you (or i) will never be consulted, it happens emergently through community dynamics. No one sat in a group and decided this, Show HN in particular has always been selective. Different things are interesting to different sub groups and they select for different things. Show HN is not homogenous. My argument is not to not post, it's to post knowing who you hope to reach and why it would matter to them, don't just post to post, that is a large part of taste to me.
