Every feed here is polled by MicroRSS itself, so the list holds only what answers and posts:
a feed that breaks or falls silent disappears from it on its own. Follow one feed, or a whole
collection as a category in your reader.
With a MicroRSS account every Follow button adds the feed to your reader, and «Follow all» takes a whole
collection as a category. The feed addresses are listed too, for any other reader.
