It’s sort of a game of blind fuzzing to try and figure out how to phrase an interest such that it will get embedded into the cluster of posts that I want to see. It’d be interesting to have a way to give scour a small handful of blog post URLs that I think should be all covered by one topic and ask “what’s the most specific interest you already have that covers these?” (And just being able to alternatively define an interest as “blog posts like these ones” directly might also be a nice workaround to remove the middleman there.)
I similarly sometimes run across other good blog posts through bluesky/reddit that I’d like scour to surface to me, and just being able to plug in one URL and have scour offer some interests that I could add which would have surfaced that post for me would be equally great.
