I went through this thought process of creating a mechanical system to find interesting content all across the web for me based on my preferences that it learned.

And I started thinking about the supreme importance of high quality data sources... realizing there's a power law there, where I could just subscribe to a few high quality people... and ended up reinventing RSS from first principles.

And then instead of embeddings we have tags...

Honestly I think we nailed it in 2005 :)
