Twine is a system for collecting and managing semantic information. A "twine" is a semantic category that you can use to collect bookmarks and information nuggets. Twines can be public or private. Uses GRDDL to map from proprietary XML to RDF, allowing easy addition of items from popular sites. When new content with URLs is added, it automatically crawls the URLs.
In essence, Twine is a Web 2.0 version of Knownspace.
