P.S. I do distictly remember how a reply on HN to one of her earlier posts on RSS clients mentioned that her laments kinda miguided since her own feed doesn't set one very well-documented and basic cache-controlling HTTP header that most readers actually do respect; but some time later in her later post she described that header as matter-of-fact knowlewdge, no "I've learned about this one recently" remark or anything, and by that time, her RSS feed had started setting it.
While I am personally glad that now there are less infuriatingly stupid network clients around (although, again, those never really amounted to all that much load), and probably adopting a rather caustic attitude at the authors of RSS clients was the only to force them to fix things, but even then: you can do more with a kind word and a gun than with just a gun. Besides, there is some unspoken etiquette between the content servers and content readers; a server that e.g. bans you for exceeding rate-limits when you open the "Full blog archives" page and middle-click at 10 promisingly named links to read them one after another is just rude, personal opinions of the hoster notwithstanding.
P.S. Seriously, max-age=155520? Your server/ISP can't handle serving a ~190 KiB (when gzipped) file even once a day, it has to be almost 2 days? Get it off the public Internet then.
(I should note that in my crowd, references to this movie are always super-negative. "The One" gets damned to hell to eternally fight, but never win his battle.)
If someone wants to get indignant and broadcast how terrible it is that a project (Debian in this case) is so terrible that they dare have a UX issue that is probably just an oversight, then they're entitled to do that but can also expect pushback where they aren't perfect either.
