When Dave started talking about reading lists, I immediately thought it could be a great way to find new things to read and gather more information. I still think that but a new use struck me last night. Why not use OPML-based reading lists as a way to create short-term feeds for people? I characterize a short-term feed as something which has information I need to know about soon but don't really need to keep it in my subscriptions forever.
I could see this being very useful for anyone wanting to keep up-to-date on a future conference. Sure, you could easily subscribe the main news feed(if there is one) but once the conference is done, the feed will just lay dormant. Instead, why not have the conference put together an OPML file I can subscribe to which would include the main blog and then maybe start including other blogs related to the conference. It could create a foundation for the conference. Then, once the conference has finished, you can easily unsubscribe to the OPML feed and thus all of the included feeds.
I doubt I'm the first to think of this use but it came to me as I was signing up for the MashupCamp. The wiki didn't have a feed I could subscribe so I'll have to keep checking back to see when the exact dates are or I'll be hoping that someone in my current subscription list will mention it. If the camp had a reading list, I wouldn't be worried.
