I've 'pinned' over 26,000 links in pinboard over the years: https://pinboard.in/u:rabble/

I think the trick is the product structure around it. Pinboard is a replacement for del.icio.us ( https://en.wikipedia.org/wiki/Delicious_(website) ) which ironically enough pinboard years latter acquired.

The trick with both is really good browser integration, via a bookmarklet/browser extension. Then add to that a social layer which made discovery and sharing easy. Plus the creators Joshua and Maciej are in themselves pretty big old bloggers, so they had an audience of fans to start using it.

In case you haven't read it, Maciej's blog has amazing essays. https://idlewords.com/

I totally think we could make a pinboard site in Nostr, the tech is easy. The getting folks to use it and making the flow very easy would be more tricky. I think if you added each page you pinn'ed to a personal RAG enhanced LLM then you do some super interesting things. If you used one of the open source LLM's like Mistral/Deepseek/Llama you could do it in a privacy preserving way.

Any, it's a good idea.
