 SemanticScuttle is a social bookmarking tool experimenting with new features like structured (heirarchical) tags and collaborative descriptions of tags. Originally a fork of Scuttle, it has overtaken its ancestor in stability, features and usability.

-  * bundle a responsive theme (forked from [sscuttlizr](https://github.com/jonrandoem/sscuttlizr)) with minimal features, designed for cases in which this app is embedded in a larger system.
