Hmmm, looks like my twt hash algorithm implementation calculates incorrect values. Might be the tilde in the URL that throws something off. :-? At least yarnd and jenny agree on a different hash.

@lyse Yeah, I noticed that too. I haven’t double-checked my code, though. Maybe it has something to do with selecting the correct URL? I mean, these feeds don’t have any # url = fields, so maybe that’s it?

No, I was using an empty hash URL when the feed didn't specify a url metadata. Now I'm correctly falling back to the feed URL.
