Built for the .NET framework, ListRing 1.0 is now available on CodePlex.
ListRing is an ASP.NET application that allows peers to easily share custom lists of information, such as bookmarks, contacts, project tasks, software requirements, blog entries, with built-in support for RSS.
ListRing is available for free under a BSD open source license, making it free and flexible to use in commercial and private implementations. Corporate teams can easily deploy ListRing to improve their communications and knowledge sharing. It has many good examples of XML serialization and XSLT transformations, and makes extensive use of Web Services for cross-application integration.

ListRing is my way of giving back to the Microsoft Developer community, which I am always proud to be a part of. Please let me know if you have any comments or suggestions.
