  Beta

Beta marks a source we read from the outside. Reddit's API went OAuth-only, so listings come over RSS and requests are paced against its rate limit; YouTube's feed endpoint has never been documented. Both work — they're likelier to change under us.

Built-in feeds

The RSS row is a fixed catalog, each feed verified by hand. Follow any of them without pasting a URL.
