I feel like the DRY concern with RSS feeds is overstated. I can’t remember the last time I had trouble with automagically generating an RSS feed using whatever open source framework I was authoring with at the time.

But the unDRYness of RSS is pretty stark. It's literally a dupe of the list page of any website. I've often been frustrated at having to maintain two versions of the exact same content, and deal with XML, when `h-entry` exists.

RSS was invented just before the semantic-markup revolution (i.e. the end of table layouts). Bad timing.

I don't think anyone enjoys generating or reading RSS feeds. You have many alternatives, but none surpass the popularity of RSS...
