• In what different ways can links be annotated to convey useful information to a user?
• What different systems and/or techniques are available to build on?
• How might a document be annotated with additional links?

Adaptive Navigation

From Adaptive Navigation we get:

• directional guidance, e.g. "next", "previous". How is direction determined? Must it only be by the original author or publisher?
• sorting of links, based on some measure of relevance? Its easy to extra links, but how does one specify their relevance, or the goal that one is working towards?
• changing anchors, using symbols or colours to indicate their target (e.g. in-site, off-site) or again based on a measure of relevance
• hiding or disabling or removing "non-relevant" links

Direct Link Annotation

• Adding title attributes to anchors during authoring to add description/comments
• Dynamically fetching information to populate title attributes, e.g. mattb's script on hackdiary fetches del.icio.us top tags for that page
• popup menus triggered by mouse overs, hover, or link selection offer a richer means of annotating links
