Oh man, the perils are endless. Back when I worked on an RSS aggregator I wrote a list. https://docs.google.com/document/d/1cvq67iQpk2C7ufOsefsfKnGCXeUIv46NQHbnHkm8PtU/edit?usp=sharing https://docs.google.com/document/d/1cvq67iQpk2C7ufOsefsfKnGC... A few comments on your list: 2. People got suuuuuper confused about this. I agree several kB is too long, though I could see a case for allowing a (reasonable length) URL, as that's a natural ID in some environments. 3. Yeah, basically if there's a fast rate of publishing relative to feed length you have issues. Another way to handle this would be to say the feed must have the last X days of content, and interested readers have to check back at least that often. Not a problem for always-on aggregator sites, though it could be an issue for occasionally-connected clients (eg, smartphone standalone app) 4. To be fair that's a feature in a lot of cases. Some sites have to monetize content somehow or other. 5. Or share buttons... 6. IKR?! For all my complaints I still wish RSS was used more!
