alt Hacker NewsOn a similar note, I maintain and grow a manually curated collection of personal blogs with valid RSS feeds: https://minifeed.net/blogs
The criteria is simple: human-written (as much as I can validate myself), in English (for now), with valid RSS feed, and not a micro-blog (so, more than just feed of links or short tweet-like messages).
Similar to Kagi's Small Web viewer, or StumbleUpon-style viewer: you can get a random listing of blogs [1] or a random listing of posts from all blogs [2]. Feeds and posts are indexed, so full-text search works across all blogs. When possible and permitted by robots.txt, text is scraped for searching, so even if some text is omitted in the RSS feed by the author, search should work.
Though I do plan to implement a similar "view one random post at source" kind of view, soon.
UPD: Feel free to submit a blog, including your own! [3]
