Because the design of RSS/Atom put all of the complexity on the client (polling, state management, etc.) it's literally the same as static site generation. And by "the same", I don't mean "an equivalent but separate problem". I actually think having two separate generators—one outputting HTML, the other RSS—seems a bit wasteful. They're both parsing (presumably) the same content hierarchy and outputting it as SGML/XML-ish documents served over HTTP. One app should probably just do both (and it's easy to make your own that does)
