I'm not a shadcn user, and so as with any project I'm not familiar with, I'm looking to see if if it's interesting to me. If the post is thoughtful and clear and I like the sense I get of their perspective on programming, then great, tell me more. No guarantees but maybe the writer is someone whose software I'd like to use. Claude doesn't tell me anything except that the writer used Claude.
It's the same as with too marketing-speak, which conceivably this is. Maybe the actual work is good but Sturgeon's law, it's probably crud. If I really needed a UI library or whatever right now then maybe I'd dig deeper but in casual browsing HN mode? No time, catch them later.
So maybe all your maybes but who cares? It's not AI that made me think badly of them: I think badly of all software by default and it takes more than Claude to change my mind.
