For a while I worked on a news application that depended on RSS, and a client needed their number of news sources radically increased for their international customer base. I discovered quite a lot of news sites around the world apparently still had a dusty server in a rack (or on a shelf) somewhere spewing out a feed, completely untouched for a decade+. You wouldn't find any links to it in the current UI, but there it was running on its cron job like a good little piece of software.

The problem was when the feed breaks, nobody remembers they had one in the first place...
