Neat! I subscribed via RSS. Can you expound on what exactly the criteria are? I'm assuming it's subjective, which is fine, but since almost all submissions are on the front page for at least a few seconds, I'm curious how this part works. Also worth pointing out (maybe there's another product for this): I would also be interested in things that maybe made the front page but I still missed, perhaps because they were only on the front page for a few hours.
I try to be the less subjective as possible, I only list recent posts, not associated with a company, not on a popular topic, somewhat related to tech, works without cookies, less than 5 up votesand it looks like a blog. If you verify all those, this is pretty likely to be included
Would you consider posting the individual blog posts in your rss feed? Use the original text, link through the original url, and maybe add a header or footer with HN link.
This way you don't have to leave your rss reader if you just want to read the article/post, which is kind of the point of the rss reader.
