Is SUP appropriate for people who only publish a small number of feeds, such as an individual blog?
Since SUP works by aggregating update information (or “pings”) for a large number of feeds into a single SUP feed, it does not make sense to create a SUP feed for a single RSS or Atom feed. Fortunately, feed providers can easily delegate to a shared SUP feed hosted elsewhere. To make it easy for small publishers to add support for SUP, FriendFeed now offers a public SUP feed which anyone can use to publish updates. Although this shared SUP feed is provided by FriendFeed, it can easily be replicated by other services, the data is freely available, and feed publishers could easily switch to other shared SUP feeds, so there is no lock-in to the FriendFeed service. Benjamin Golub’s simple, open-source blog software provides a great example of how this can be used to to add SUP support with only a few lines of code.
