HN is an unique place to get feedback for your own work. I certainly have opinions about others work as well but usually I keep my mouth shut and go back to work.
However—by your own description—HN is a place where you solicit feedback but can't be bothered to extend the same courtesy to your peers.
Think of it like a conversation. If I approach you asking for feedback on my projects but never return the favor, does that not seem suspicious?
For my own projects I like to get all the rants as well. Gives a broader picture. I have a feeling that HN doesn't have a very strict etiquette.
To be clear, I take nothing away from what you've done here: More tooling options are rarely—if ever—a bad thing and your presentation of riot is beautiful and clear, very well executed.
