Today's Google Reader Shared Items
This pipe allows you to generate a feed that contains a subset of your Google Reader shared feeds. For example, you can create a feed that has the items that were "shared" in the last 24 hours. The reason that this is necessary is that Google doesn't make the "shared date/time" available in the feed, so there is not way to tell when a given item was shared.
In order to use this pipe, you will need to save off your Google Reader Shared Item feed periodically, and make it available on a publicly available web server. This pipe uses the saved feed to determine which items are "old", and doesn't include those items in the returned feed.
