I find that rss output is just part of good architecture so it’s sort of something I’m going to make even if no one uses it. Because I want to have some static form of syndication that processes can check.
Of course there is some nominal cost to exposing the uris or something, but anyone complaining about this would be weird to complain. Especially given all the other odd feature requests going on.
The static site generator I use (Pelican) can produce templated RSS feeds that are exactly to my liking. If I can use that off-the-shelf stuff for a small blog, then it's trivial to put together a template and plug in database data on relevant events. Could even just run a cronjob that tracks the site daily and forget about it, most people would not care.
