Folksonomy?

What is a folksonomy?

Thomas Vander Wal, the information architect credited with coining the term "FOLKSONOMY".
Normal ordinary humans = folks
Scientific Classification = taxonomy
In other words, a folksonomy is a user generated taxonomy used to categorize and retrieve Web pages, photographs, Web links and other web content labels called tags.

Why do I care?
Folksonomies, or tagging, can help you locate information that has been selected by other humans who share the same interest or expertise. Search engines are not human (of course!) and there fore not very intuitive.
