I can't understand it. Clearly someone cares because like you say the comments are always upvoted. But why anyone cares I simply don't know. It just feels like attention seeking behaviour to continue posting it.
Isn't posting any comment on a forum like Hacker News "attention seeking behavior"?
Seems like quite a different level of attention seeking by posting the exact same prompt result, every time there’s a new model, that links to their own website.
Linking to https://tools.simonwillison.net/markdown-svg-renderer?url=ht... should be pretty inoffensive (I started habitually linking to that after people kept complaining about linking to my blog) - that page renders Markdown with SVG embedded in it, but doesn't link to the rest of my site at all.
