You might be interested in https://hnblogs.substack.com/. You could use its RSS feed as an input source. I'm not sure exactly what the author's filtering process is--I think it's partly filtering out domains that are known to not be personal sites and then going over the remainder manually, or something--but I read it every day, and while I usually don't follow any of the links, every once in a while I find something golden that I never would've found otherwise.
