You may enjoy sites like Minifeed[1], Kagi's SmallWeb[2] and Wiby[3]. These are some neat sites that let you discover random blogs and personal sites and are very fun to sift through and read something interesting.

I think filtering by HN front page, and then filtering out the items you want in an RSS feed is a good combination that makes it easier to filter out the noise.
