There is no reason to require any particular comparison algorithm. One application is going to compare them the same way every time. Two different applications may reach different conclusions about two equivalent identifiers, but nobody cares because AT WORST the result is a bit of inefficient use of storage.
It is worse than that. To give a concrete example: Radio Userland's aggregator will not present to you an item that you have seen before, no matter how different the current content is.
So? They will just go out of business, as people find better aggregators or editors.
Leaves a bit of space for my Open Source, BSD licenced BlogEd to make headway.
That was just one example. NetNewsWire will correlate messages with equivalent ids and optionally present HTML diffs.
Identifying which messages have been seen before and which ones have not is a significant area where the user experience with current aggregators has been suboptimal.
