Does anyone know why RSS feeds sometimes repeat themselves? Every so often I get the whole last [however many, like a week's worth] posts all over again, all at once, like it was just downloading a newsgroup for the first time or something. I see this sometimes in feeds synced to LJ as well as just ones I subscribe to with Thunderbird, which says to me it's something originator rather than receiver related.
