Trailmeme is an interesting new service that could be described as social bookmarking meets social mind mapping. The basic idea behind Trailmeme is that we all have our own way of connecting the things we find on the Internet when we research a topic. Trailmeme provides a way to record those connections and publish them as a mind map or flowchart that Trailmeme refers to as a "trail." When you publish your trail publicly other visitors to Trailmeme can "walk" the trail you created. Walking a trail means that you follow the map of labeled links created by another person.
