Fever, Shaun Inman’s unique, self-hosted news reader, automatically deletes news items that are not Saved after 10 weeks. This setting can be adjusted in Fever’s Preferences > Refreshing pane, with options of 2, 4, and 6 weeks instead. I imagine Shaun implemented this rule because Fever probably puts an at least noticeable load on one’s bandwidth, storage, and MySQL server. It isn’t a deal-breaker for me, personally, but it is certainly worth nothing for potential customers.
