There are guidelines for what Show HN is supposed to be. This site pretty much fits the bill.

> Show HN is for something you've made that other people can play with. HN users can try it out, give you feedback, and ask questions in the thread.

> On topic: things people can run on their computers or hold in their hands. For hardware, you can post a video or detailed article. For books, a sample chapter is ok.

I am glad to see work from other hacker news members. When it isn't interesting to me, I find something else on the internet or IRL that is.

Great point. While not everything is appropriate to share in response to someone else's "Show HN" post, I've definitely seen (and appreciated) others linking similar projects. It usually is in the context of saying something like:

- I tried this too, and can appreciate that you solved way harder things than we expected to have to deal with - I had this idea too but like your execution

I think it's very fitting, especially since we are celebrating not just the idea, but the execution that someone did to be able to show it off here.

Same. I love it when I see two creators of similar projects mash up ideas in the comments. That's the spirit of HN imo.
