Aggregators
Aggregators reduce the time and effort needed to regularly check websites of
interest for updates, creating a unique information space or "personal newspaper." An
aggregator is able to subscribe to a feed, check for new content at user-determined
intervals, and retrieve the content. The content is sometimes described as being "pulled" to
the subscriber, as opposed to "pushed" with email or
IM .
Unlike recipients of some "pushed" information, the aggregator user can easily
unsubscribe from a feed.
iTunes is an example of an aggregator .
