Add random offset to expiration date for syndication feeds, so the server don't saturate dial-up connections. If the server is connected using a low-speed link, the link can be saturated and the downloading of the newsfeeds can timeout if done simultaneously. Adding a random small offset to expiration times can improve this problem. As the value should be calculated every time the newsfed is displayed, maybe a deterministic calculation would be better option. For example, using a quick hash from newsfeed title, may provide a unique number always. Pending to write proof-of-concept.
