there's an #11ty repo you can use that lets you create an #rss aggregator, those of you who have been around a while might be reminded of dave winer's River of News, but this isn't that sophisticated.
but it is probably a really elegant way to build an impromptu pipeline of posts for future use like how i have saved articles and posts tagged "feed-seymour" in readwise that are stripped to markdown and put into a RAG pile for an AI?
