Today, Spurl came out with
Spurl.net streams. Quote from the Spurl user forum:
"Spurl.net streams are a new and improved way for publishing spurls and working together in groups, gathering links on a given topic. A user can create a Spurl.net stream on any topic and allow others to contribute to the stream. When creating a stream, a user connects one (or more) of his existing categories to the stream. All spurls to that category there after are added to the stream.
There are three types of streams: An "Open" stream allows any user to join as a contributor without anybody's permission. A "Limited" stream requires an approval from the stream owner before a user can become a contributor. A "Closed" stream does not accept any additional contributors.
When a user joins as a contributor, he or she can connect (one or more) existing categories to the stream, or have Spurl.net create a new category that is automatically connected to it.
Within a stream, anybody can view the spurls, sort them by date, title or popularity and search them, using all the same advanced possibilities as available when searching one's own spurls. This can make a well-crafted stream a highly valuable resource about a given topic, allowing its contributors to build an advanced search engine with custom, hand picked content.
And a Spurl.net streams' contents can of course be syndicated via RSS, Atom or a Javascript feed."
