From my perspective, I have two projects that I have considered [Show HN] posts for. One of those I have not yet posted because I have not yet completed writing up the process I used to construct it (a non-trivial project in an artifact). Without that commentary it falls into a different class, which i agree shouldn't be outright excluded, but is of less general interest. The other project I think some people would be interested in it just for what it is in itself, I just want to add a bit more to it.

Perhaps [Show HN] for things that have commentary or highlight a particular thing. It's a bit nebulous because it gets to be like Wikipedia's notability and is more of a judgement call.

But if that is backed up with a [Creations], simply for things that have been made that people might like or because you are proud of your achievement.

So if you write a little Chess engine, it goes under [Creations]. If it is a Chess engine in 1k, or written in BrainFuck, or has a discussion on how you did it, it goes under [Show HN]

[Creations] would be much less likely to hit the front page of course, but I think there might need a nudge to push the culture towards recognising that being on the front page should not be the goal.

For reference here are the two things, coming to a [Show HN] near you (maybe).
