thanks! and, interesting. I do see that buzzing.cc posted that one, but I can't find any evidence in our logs that we ever saw it in seattletimes.com's RSS feed.

any chance you know of another example?

ahhhh, I see. true! the AP id we generate is only based on the post's URL itself, it doesn't also include the site that's posting it, so yeah, they'd collide.

any chance you have a recent example of a collision? I've been looking but haven't found one yet.

hmm! looks like this is just an aggregator? that's been a pretty established pattern in the web for many decades. the posts seem clearly like links to articles on other domains, ie it's not trying to pass them off as its own, right?
