Abstract: Among other things, the ability of people and entities to produce, distribute, and use text, images, video, and other items of digital content is enhanced by providing software tools that enable them to (a) clip items of the digital content on any platform that is capable of presenting the digital content, (b) store copies of the clipped items along with copies of items clipped by other people or entities, in a common storage place controlled by a host, (c) form and store meshes of tags to represent their mindsets about items of content. The tags include primary tags that express their direct observations about the content and secondary tags that express their observations about the primary tags and the secondary tags. Meshes of the tags are made available to the people who formed them and, if permitted by them, to other people and entities for use in understanding their mindsets and in producing, delivering, and using digital content.

Abstract: Among other things, information is received that represents tags and tag relationships associated by users of content with items of content, and rankings of items of content are derived based on the tags and tag relationships.
